But just posting about how you feel awful and how life is shit and full of injustice isn't gonna help you.
I'm not having a go at you - I know from experience. I used to post whiny shit all the time as well. It feels like it helps at the time, but it doesn't really. It just encourages you to keep sitting in your little bubble of misery.
Can't you meet anyone IRL? I know you're shit at socialising etc, as most of us are. But what about an autism group or something?
