I think that a lot of this depends on your background and how you tend to think about things in general. If you have a lot of family trauma and you find that it is helpful for you to understand what went on a more conceptual level, then I think that psychoanalysis might be more helpful, but if you find that you are constantly overwhelmed with emotions, and do best in or might benefit form a structured environment then I think you might find CBT more helpful. I know that a lot of creative and more academically minded people tend to prefer psychoanalysis. But I don't think that this is because it has more merit as a therapy, I think it just has to do with it being more open to one way of thinking than another. Same with CBT, some people just think in away that fits homework assignments and predictability better. I guess the question is do you find creativity of routine more soothing?

But I think what other people have said here about finding a t who you connect with is the most important.

Also if you find that you are feeling emotionally closed off I think it would be a good idea to get to the bottom of why that is happening. Does your T remind you of someone or something that would make you hesitate to be open, or is there an issues that you need to talk about that you are trying to keep yourself from working on because it feels scary?
