I don't think you're being dramatic at all. That's a really tough situation. Are your friends all drug users? If you've recently stopped using drugs, losing some friends is a pretty common side effect.

Lots of people are feeling alienated, perpetually. It's just a consequence of how our society is laid out. I'm not saying this to downplay what you're going through, but to highlight that it's a problem lots of people struggle with, which means there are solutions out there.

Some people I know get a lot of socializing done through the web, where strong online communities can offset that sense of loneliness. I personally don't think that's the best solution, but you're here in lemmygrad. You have comrades that care.

More helpful would be to find some hobby groups. When I had to kick a drug habit, I spent a lot of time at game stores, getting involved in tabletop sessions. Maybe you have a hobby you could find a club for?
