I think it's easier to find a Psychiatrist.

You need to outline what side effects you're willing to endure. It's better the doctor has some idea of what you'll tolerate then blindly taking stuff. Or, if you do agree to take medications, make sure you know what the side effects are and know when to quit them if they become unbearable.

Getting to the root of the problems will help a lot. When you're stressed it's easier to get mood swings. If you see a therapist, try to focus on things that you know need to be resolved. The longer you avoid a problem, the harder it is to heal from it. When you're starting intensive therapy, it should hurt more in the beg-middle as you're forced to look at the behaviors and memories associated with them.

BUT! Most importantly, find a therapist who will really listen and you can see indefinitely as long as they're in the area. Switching can disrupt the healing process.
