I agree with Pat, and I was thinking along the same lines.

See if you can find a clinic. I know there will be people there, but you have been able to get out to other places around people (albeit with unpleasant results) but this will be worth the effort if it can get you help. I would think they would understand your difficulty of being around people and have some solutions to that, as it is part of the illness they would want to treat, but it may take some extra effort on your part. But it is possible that some sort of anti-anxiety med might help you with those symptoms and allow you to pursue the other help you need with much greater ease.

You are going to have to have some faith that help is available and that being in an uncomfortable situation may be the only way to avail yourself to that help. Even so you can search for a way to make it the least uncomfortable for you.

Good luck, and welcome to the forums. Continue to post here for suggestions, understanding and support.
