Wow this is exactly me when I was 23 too.
I'm not 100% sure if your post is serious or just kopipe, but I'm going to reply to your post earnestly as a fren because maybe it helps you or someone else.
Please don't shave/epilate/depilate/wax/pluck/etc your body if it doesn't take it well. You can try things out in small patches just to test, but don't do it if it reacts badly. I know it's hard but your skin will be less pitted and scarred and hurt and just be nicer this way. You can try approaching it with the mindset that at some point you'll be able to remove the hair without hurting your body and in the meantime you're just saving your skin for that day. Maybe this path leads to permanent hair removal, laser or electrolysis depending on your hair and skin, and this way you won't have ingrowns or anything, but maybe you don't want to go down that route so far, that's okay too.
If you haven't already, you can try trimming your body hair down instead so it's very short but not shaved smooth. This will substantially reduce ingrowns. It will still be prickly to the touch, at least in one direction, but it will still look and feel much nicer than razor bumps and stuff.
You can also try plucking your upper lip with tweezers - even with my bad skin that's prone to ingrowns, it takes it okay. If you don't pluck everything that's fine, doing a little bit still reduces overall shadow and makes it easier to shave too.
I know you're not trans, but birl pills can also sometimes reduce body hair but I haven't seen a big change in myself in that regard. There are some stray body hairs that haven't grown back since I started, but that's about it so far. Maybe my T levels are still too high to see a big change with this, so I'll keep monitoring this myself.
You can get better at not being depressed when you see others. It takes a mental resilience that I struggle with myself sometimes. I think browsing /what/ helps for me, sometimes pictures are posted and it hurts but I try to just be happy for them and make the best of my own situation and try not to compare myself too much. I'm not as good at it as them, but that's okay.
It's the hand you're dealt, things can be really difficult sometimes. That's the way the しょうがない crumbles.Post too long. Click here to view the full text.
