Sorry, no suggestions because I'm going through basically the same thing, but I wanted to tell you what seems to be my new catchphrase on PC: you are not alone! By the way, with your anxiety being that bad, it sounds a bit like you qualify as being "disabled" in a similar manner as I am, at least here in the UK, so I hope you get the appropriate support; the support, financial and otherwise, has been incredibly helpful for me. Essentially, you'll want to get some help, but I do fully understand how difficult that is, because if you're so anxious you can't go out, then how can you go out to get help? It's an enigma, but it can be alleviated with some support from friends or family, and determination to make a change. Personally, I find anxiety can sometimes hold you a prisoner, but there are in-fact no bars; you can escape anytime you like. That's my analogy anyway, which is probably flawed, but I like it. :P One thing I recommend, is to use what you have: the Internet. You have so many sources online for ways to deal with anxiety, support groups (if you can get to them), places like these (generally for support, not as a treatment), and the ability to E-Mail people such as your Doctor, if it's allowed where you are. If not, you can probably write a letter; over here, I sent a letter to my GP for the same or similar reasons to yours, and I found it very helpful; the letter has been used a few times as reference and saves me a lot of hassle. [: I'm almost 27, by the way, and wonder whether I'll be at home for the rest of my life, too, especially alone. I don't even have my own place because of the anxiety linked to getting that sorted, plus some other things, such as waiting lists, finding a decent place, my other MH issues blah blah blah digressing blah blah blah.

Best of luck to you and please remember "You are not alone!"
