Like some of the others, I've been doing this for years. I say I have a headache, or some other lie to get out of going somewhere. I believe it's a function of my depression. And isolating just makes depression worse. If I can just go across the street to buy something at the corner gas station, then I feel a little better. I don't have a car, so if my friends come here and pick me up, then I might go out. If I have to go on my own and get on a bus or walk there, it's so much harder. I've even done this with work, and got fired from my last 2 jobs over it.

When you go out, is there someone you trust who can go with you? I'm much better when my friends pick me up and we go together.

I would suggest doing a little at a time, and talking to your pdoc and your T about it. Maybe they can find a way to help you. Isolation is not good - I know from experience.
