I wish to counter your question, "How low must I sink [for people to accept me]?" Instead consider 'how high must your raise yourself.' The first statement implies to me that you are waiting for positivity to arise in your life - particularly socially. In truth however, attaining and maintaining such requires a great deal of hard work. Things have improved for me but it took effort to get here.

I agree with a few things pointed out and suggested above. Namely, consider instead what positive things you have going for you and try to translate what works for you on the internet into what might work for you in real life. In fact, I suggest putting the internet on the back burner for a while.

What has been successful for me?
- volunteering
- support group
- finding a social group pertaining to my interests (a weekly art and coffee meet-up, and a monthly get together to play board games)
- getting to know my neighbours
- even pleasantries exchanged with my grocery clerks and cashiers
