Loneliness in ADHD: Why Does It Happen, What Can Be Done?

On Saturday evening you look at your phone. No messages from anyone, and you have not written to anyone either. All week you waited for an evening alone at home, but at some point the comfort turns into something else: the feeling that nobody is calling you, and that the one who is not calling is, in fact, you.

The name of this feeling is not always being alone. Most of the time it is feeling lonely, and the two are different things. To understand loneliness in ADHD, this distinction has to be set down first.

Being alone and feeling lonely

Being alone is a situation: there is nobody else in the room. Feeling lonely is a perception: the gap between the relationships you have and the relationships you want to have. In loneliness research this distinction holds a basic place, and loneliness is defined there as perceived social isolation (Hawkley & Cacioppo, 2010). You can feel lonely at a crowded table, and you can have a very good day without talking to anyone.

In ADHD these two things are intertwined. On one side there is a real need to be by yourself; as I described in the article on the social battery, it is possible to love people and still get tired. On the other side relationships break off on their own. From outside the two look the same, from inside they do not.

In your place, I would look at this: how do I feel after an hour spent alone? Did I fill up or drain? If I filled up, this is a need and it is being met. If I am empty and there is a feeling inside me of not being able to reach someone, the matter is not being alone but the weakening of a bond.

What in ADHD feeds loneliness

On the friendship side, the difficulty often shows up not in making friends but in keeping them. Calling someone requires remembering something to be done later at the right moment. This is called prospective memory, and it is one of the areas that is hard in ADHD. Time adds to it: what you thought was two weeks turns out to be two months. I wrote the details in the article on ADHD and friendship; here let us look only at the result: you have not forgotten anyone, but from the other side you look forgotten.

The second source is the fear of rejection. A message left unanswered or a plan that gets cancelled can cause disproportionate pain. Rejection sensitive dysphoria is the name for this. The meta-analysis by Beheshti and colleagues (2020) shows that difficulties with emotion regulation are common in adult ADHD. Its everyday counterpart is this: first the story the behavior creates hurts, then withdrawing feels like the safest way. And when you withdraw, the bond weakens a little more.

The third is the trace from childhood. In the study by Normand and colleagues (2013), the friendships of children with ADHD had lower closeness and satisfaction and more conflict. This study was done with children. As far as I know, there is little well-designed research that directly measures loneliness in adults. So I infer the mechanisms in adult life from known symptoms; I do not present them as a measured finding.

The self-feeding loop of withdrawing

The sneakiest side of loneliness is that it grows itself. You answer a message three days late. You are ashamed because you were late. Because you are ashamed, you put off the answer even more. A week later the message has become so heavy that not sending it at all feels easier. I took up this chain separately in the article on shame and self-compassion in ADHD.

There is also masking. Trying to look attentive, organized, "normal" at a meeting-up is very tiring, and the cost shows up when you get home. Then the thing that does not want the next meeting is in fact this tiredness, not the people. Masking is a separate subject but its relation to loneliness is very direct.

Stigma plays a role here too. Someone who hears sentences like "everyone is a bit like that" or "you're looking for an excuse" a lot stops explaining after a while. When you do not explain, closeness does not deepen. In the article on stigma you can find how to answer these sentences.

There is also a study on the wider effect of exclusion. In a study that followed a group born in England in 1970 up to middle age, part of the relationship between childhood ADHD traits and mental distress in adulthood is explained by social exclusion. It is an observational study and does not prove cause and effect. Still, it is a reason not to see loneliness only as the person's shortcoming. The details are in the article on social exclusion.

Small adjustments that ease loneliness

Increasing the number of friends is most of the time the wrong goal. In your place I would set up a small system that can carry the relationships you already have.

• A weekly contact hour. For example, Sunday evening, 20:00-20:10. For ten minutes, write one sentence to three people: "You came to mind this week, how are you?" It does not have to be the same three people every week, but let the hour be fixed. A fixed hour removes the decision of "when should I write".
• A call once a month. A recurring entry in the calendar: "Call X". If you cannot find anything to talk about when you call, "I thought of you" is enough.
• Side-by-side activities. Instead of sitting facing each other and talking, a walk, working together, cooking. Since I like walking, this seems the easiest way to me. Doing something even when the conversation does not flow lowers the pressure.
• Special days in the calendar. Birthdays, get-well wishes, holidays. The details of this are in the article on forgotten special days.
• A one-sentence explanation. Instead of a detailed apology: "If I go quiet, it's not because I'm angry, it's that I'm weak at letting people know. You write; even if I can't reply right away, I read it."

A ready-made sentence also makes it easier when you go back to a message you answered late. Say a friend wrote four days ago, "are you free at the weekend?" "I'm late, sorry, would this Saturday afternoon work?" is enough. You do not need to explain why you were late. An answer arriving matters more than a perfect answer arriving.

If you want to meet someone new, I think recurring settings are easier: a weekly class, a walking group that meets at the same hour. The setting takes on the burden of planning each time, and you just go. The article on meeting new people looks at this subject in more detail.

The voice inside you when you feel lonely

"Nobody likes me" and "I have no system for keeping the relationship going" are different sentences. The first makes you smaller and gets nothing done. The second describes a problem and has a solution. You can look at the same event with two sentences, and which one you choose determines your next move.

As someone who keeps a diary, I can suggest one thing: write the days you feel lonely as a short note. When did it start, what had happened, how did you feel after the hour you spent alone. After a few weeks a pattern comes out, for example on Sunday evenings or after a busy week. Seeing the pattern lets you read the feeling not like a fate but like a calendar.

When loneliness points to something else

Not every feeling of loneliness is explained by ADHD. If withdrawing from people has been going on for weeks, if things that used to give you pleasure no longer do, if sleep and appetite have changed, the picture may resemble depression. If there is anxiety and a racing heart lasting days before a meeting-up, social anxiety also comes to mind. Both are common together with ADHD and both have treatment. Talk about diagnosis and treatment decisions with a doctor; this article does not take the place of that assessment. If you have thoughts of harming yourself, call 112 without waiting or go to the nearest emergency room.

What is left for me

I think the loneliness of someone with ADHD is less a lack of interest than a lack of infrastructure. Relationships depend on remembering, timing and a balanced energy, and all of these ask for extra effort in ADHD. Accepting this and moving the infrastructure outside, into the calendar and fixed hours, works much better than "trying harder".

Building a crowded circle also seems unnecessary to me. I think regular contact with three or four people protects more than irregular contact with thirty, but I do not have measured data for this; it is my own view. Not every relationship lasts anyway, and you are not to blame for every break. This is how I make the distinction: a relationship you lost by forgetting is worth working on, and for a relationship that ended naturally you do not need to wear yourself out.

Feeling lonely is nothing to be ashamed of. The feeling of shame makes you hide, and a hidden feeling makes it harder to send the message. Keep the shortest sentence ready, and send it to one person this evening. Even if the answer does not come right away, the bond will have gotten a little stronger that day.
