My T is hammering away the idea that in order to recover, I need a support system in place beyond our therapy( stubborn me says no, I can handle it by myself, I've always taken care of myself, etc.....)

So, I'll put this out:

I am people avoidant and total isolationist (hide when the doorbell rings )
I have no family support and zero friends ( yeah, I'm a loser)
I don't go to churches
I don't do social activities because I am avoidant, panic ridden
I looked at a support group for my problem but I am afraid someone will discover why I am going as the med director is a neighbor and our kids are in school together

So, how do you begin to build a support system when you live in your own world and are fearful of people?
