Therapy can help when you know you're going stuff you don't want to do, but you don't know how to break the cycle. Cognitive behavioral therapy helped me a lot. One of the things I learned was that it's possible to feel a certain without needing to act on those feelings. For example, if I'm mad at someone, I don't have to yell at that someone. If I'm scared that all my stock investments are tanking, I don't have to sell my investments. And so on.
