Rap, I think that is pretty normal. A lot of our problems benefit from structure. I know for a fact depression does. Like you, I can be fine as long as I'm busy, but I get in trouble with time on my hands. I've never figured out how to reconcile that, because just by nature, I require a lot of time to myself -- even though oftentimes it's the worst thing for me.
I hope things get better for you soon.
