We do have a good support system in the UK, though our current government is slowly dismantling it and labelling those of us who rely on these benefits as "scroungers". In the last year, I've read many news paper articles about people missing limbs, or suffering from severe mental handicaps as being 'declared fit for work' by the governments goons in white coats. It's actually appalling, and rather terrifying for those of us who have no other source of income.
On the topic of groups, it may interest you to know that people with aspergers tend to be able to socialise much better with other people on the spectrum. I made a friend from the US who writes a blog about her life with aspergers and she told me about her first ever group meeting which was only a few months ago. She too had put off because she doesn't like being around people, but she said that once she got there it was like "returning home and hearing people speak your native language for the first ever". Apparently it was very comforting for her and the others in the group to be around others on the spectrum because they all just kind of 'got' each other, plus there was never any awkward hand shakes, or body/eye contact required or expected haha.
Though that said, I've still not gone, but I think I would like to just to see what it's like. I gave up trying to master neuro typical interactions a while back, they don't try to learn my ways so why should I learn theirs?
