Greetings, dear Pam (and you, too, dear Sizemik)... and peace to you, both!
I hate to sound trite but... "this too shall pass." At least, the "I no longer have any friends," part. I say that because I've been on this board for many years and I have no doubt you can/will make friends... if YOU want to. Very few here have been able to avoid that and have done so either because they don't really want to make friends... or they're the kind of people many would call jerks.
As for your anxiety, some folks here might help with that, too, but it could take some time... which you may not have. So, you might need to deal with your anxiety/agoraphobia in a more tangible, professional manner. You could also keep in mind that many who followed Christ were also isolated, even persecuted, because of that. Since I don't get the impression from either of you that that is contributory, however, I won't go there.
But don't give up. True, life isn't always "rosy" (and, for some, it seems never to be)... but it is rather short. Meaning... you really haven't a moment to waste. You're free from what could have been the most enslaving experience of your life. For whatever that's worth, you might want to take this opportunity to rejoice... and start living for a change.
True, it's easy to sit in the house and commisserate (sp?) what was and what could have been. But it's much more rewarding to get out and do something. Even if you must start out doing it alone. You have nothing to lose, though, by doing the latter except the opportunity to spend some "quality" time... with yourself. Surely, you deserve that. Everyone does.
Again, peace to you. Truly.
A slave of Christ,
