As promised...
These books helped me with depression by controlling my thoughts. Example, it's common for people to see a group of people look at you, talk and then laugh. Some people think nothing of it, others take it to heart and may get angry if they have anger issues or sad if they have depression. They can't help but think this way, it really is natural to do so. These books teach you that the group is not talking about you and to think nothing of it. I know how it sounds, that isn't the best example, but they help. Not every chapter may pertain to you, obviously, but they are worth looking into.
