Darkrunner,
I suffer with this too with my PTSD. I avoid friends, social gatherings, going out, household tasks that are overwelming, it can come out in anything.
what is it that you are avoiding? It's easy for a T to say just do it, it's not so easy to just do that. I have lost friendships along the way because of the avoidance issue. People don't understand if they are not suffering with this.
