I've been there & back, HQ. I'm BP I, too, & when I get depressed it's so difficult to leave the house that I don't go grocery shopping until I'm virtually out of food. The only place I really feel safe is inside.

The only advice I can offer is what I learned in cognitive behavioral therapy. It suggests taking things incrementally. First going out to the car. The next time, getting in the car & driving through the parking lot. The next time, parking & walking up to the store's door...etc. It a way of progressively getting over your agorophobic tendencies...or so they say. I know it's easier said than done from my own experience, but when I start feeling a bit better it's a good way to start emerging from isolation.

I wish you luck & hope you can get back to your regular routine soon.
