I'll tell you what I relate to, but first let me tell you: even if I don't feel alike in some things, I can see how what you're expressing is completely justified.
I do really like being alone, as you do. From ages 10 to 16, I had been a recluse. I put myself in front of a computer, all day long. I just went to school, socialized a bit there and came back to be alone. I also had a lot going on, some things I cannot even tell to strangers online. However, at home not only I felt safe: I just didn't feel like I needed to be anywhere else, nor with anyone.
Sometime when I became 16, I went on an cultural exchange to Germany with some classmates. Now, there I had to socialize all day long, go out and about with them. I became noticeable. I made friends. It didn't feel nice nor bad. However, I also had problems just saying no so with the friends I made I started to go out and socialize. I made even more friends. With each and every one of them, I felt I was becoming another person. I felt, I was changing too quick in between people. I felt like I wasn't being genuine, I felt some kind of trickster, an evil person. I was disgusted by myself, because I thought I discovered what a bad person I was. I didn't even know who I was anymore, to be honest.
I felt overly stimulated. Thoroughly depressed. I started skipping school (here we diverge). I spent all day in bed. I started losing all the energy I had. I could no longer get up, no longer go out. Bed had become a prison and the alternative was... another prison. To go outside. To socialize. I could no longer enjoy my time alone, without being riddled with horrible thoughts. And somehow... I felt that I've had those thoughts all my life, just that I felt okay in a bubble I had created for myself.
When there was quarantine, I truly enjoyed it. It reminded me of spending entire summer vacations at home. It reminded of peace and quiet when no one was there to bother me. Not a single soul asking me anything, nobody to summon me into the real world. Now, I'm also been at home, not going out a single time for two months. However... I get messages. Calls from my therapist, from social services, from my friends. I feel bad, getting people worried. And I also know, that keeping this up only might get them to call an ambulance or the police.
I wish people would just leave me alone. People don't bother me in themselves. They can be funny, they can be nice, they can make time go faster. I've even loved somebody before. There's nothing wrong with people. What I can't stand is people having a need for me, or even worse a need for my safety and prolongued existence. I hope that someday everybody just forgot about me.
Sorry for the long response. Thanks for reading it, I hope it resonated with you.
