As far as self-help goes, I'd recommend Feeling Good and/or The Feeling Good Handbook by David Burns, M.D. They're available at most bookstores and maybe at your library...if they're not at your branch, you can talk to the librarian about an inter-library loan. I've never read the Handbook, but Feeling Good did me a lot of good. I actually bought a new copy last week because my original has been lent out to so many friends and family members that I lost track of it.
