Oh susan, I don't even know you but I would hug you if I could. I know exactly what you are experiencing because my counselor has me doing the same thing. I can't take the usual meds for social phobia and so the plan is that if I'm exposed enough to the situations that cause me so much fear I will eventually become immune to them. So far that hasn't happened for me, and actually too many exposures and I take a step back in my progress.
I'm rootin' for you. You've replied to my posts before and come across with strength and I think that is key in beating it. Awesome that you followed through even though it was hard. I'm still at the stage of running away.
I should probably take my own advice, keep going and you will succeed.
