Anxiety is a really tough thing to cope with. (Worse than depression IMO.) Sounds like you've tried meds with disappointing results. That was my experience too. (Benzo's, Neurontin) Having someone you trust in your life is huge. Tha's really good.

I think meaningful interaction with other people is one of the best things to quell anxiety. That can be hard to manage when social interaction is, itself, a cause of anxiety. Probably the unhelpful skepticism of those close to you has undermined your ability to have supportive relationships. It's a shame that some people are so ignorant about mental challenges. Unfortunately, they probably won't change. You just have to be careful who you confide things to. I've had to learn to not give judgemental people ammunition to use against me. Meanwhile, keep alert to chances to know people who are more enlightened. PC is a good place to come, in that respect. I hope you find a foothold in your struggle. Keep trying to do things that seem hard to do.
