I was in the middle of a depressive episode. I pulled into a store parking lot, shut off and got out of the car, then just started walking. I hit the sidewalk and kept going straight for a while then just turned around and went back to my car? The whole thing only took like 5 minuets. 

I have no idea why I did this. My brain was on auto pilot. I've never done something like this before, it's new. Is that supposed to be part of a depressive episode or is this something else?
