I'm sorry you've been feeling that way.

One way I use to combat things like that is finding a passion or something you're really interested in and just going for it.

I'm not saying you have to go that far into such a passion in a week or something, that would probably be obsessive or something, (although if you are obsessive about a passion, I don't think that is such a bad thing).

I like your idea of just being busy with a to-do list. I would make sure some of the things on it are fun.

I think you can do it.
