Many people who are perfectionists and also think they aren't good enough end up depressed. The most likely reason is that they have been thinking negative thoughts about themselves for so long, they begin to think that their world will never change, that nothing can make them feel better and more optimistic. I don't know how people can be satisfied with anything. Everything always seems like it just isn't good enough. I feel like if I could just find the perfect thing, then everything would be perfect. But it never is. I'm always waiting for something to come along and make everything better, but it never does. Life is just too frustrating.
