For what it is worth, it sounds like you have some version of agoraphobia. I used to have an ultra-advanced case of it. I took anti-depressants and did talk therapy for years, with really no impact. Then, I did "behavioral therapy" for about 7 weeks (not very thoroughly I might ad as I was/am still clinically depressed). I cleared up the agoraphobia completely however in very short period of time. It turns out that behavioral therapy is overall VERY EFFECTIVE for this particular problem. Naturally, your condition may be quite different, but I would very much encourage you to research this diagnosis/remedy as being possible very helpful. For me, it had gotten so bad that I almost completely stopped leaving the house for about 10 weeks. You would think that getting over something like that life would seem all good, but alas...
I wish you the best, tell us how it goes.
