Hi Op,
I'm really sorry you're feeling like this.
I'm not quite in the same position, however I have been experiencing extreme isolation/loneliness/detachment (pre-covid), during covid and now.
I'm fairly new to the city I'm living in now (4 years here), but have failed to form real meaningful friendships and have had a disastrous relationship history. I'm single, childless (not by choice), not living close to my family and I have one friend (who is an ex partner), I'm 39.
Pre-covid and during it, I think I'd developed alcohol addiction to some degree - I used to get drunk on my own frequently because it was 'something to do' ...otherwise I'd be lying in bed waiting for Monday. That's how bad it was. I was in tears most days. I'm fairly functional in a sense that I've managed to keep my job and work, not get sacked but I feel life is a real slog, and I don't know how much longer it'll continue to be like this. I can't rely on my one friend and I try to be a positive influence when around him.
I was married previously however it was a really dysfunctional relationship.
I've done all the possible solo activities/hobbies there are, and I'm bored of my own company. It's been 8 years on /off like this. I want someone to do nothing with, I can do other stuff on my own.
I have zero faith in relationships and would probably end up in a shitty one as I feel so desperately lonely in the evenings/weekends. I often think if my friend wasn't around in my life, I'd die and nobody would find out for days.
Lost touch with school friends/moved around a lot for an partner. I feel rootless. I've no idea if it'll ever get better
OLD is an absolute cesspit, and when you're in the wrong headspace it will bring you down even more.
