Which type of therapy, you ask? That's hard to say. But you can start off by trying to find either a good psychiatrist or psychologist to start with. I always look for recommendations. Ask your doctor can he/she recommend someone? It's hard to find a good one, and you may have to visit with a few before you find the right one. But it is SO worthwhile when you find the right one. I finally found a great therapist, and we don't always just talk about anxiety or depression. I tell him issues like a fight I had with my friend, and a conflict with a neighbor. (Both of which are now resolved)

Which medicine, you ask? As far as medication, you're not an anxious, nervous, worrying, wreck like me so you probably don't need a benzodiazepine, like Klonopin or Xanax. But you might benefit from an antidepressant.

This is the part of your post that made me feel like you may benefit from an antidepressant: "It has also made my emotional life more "dull". It's like all the feelings that one experience in life is just greyed down and less vivid. I can't really feel intense satisfaction, content, love, sadness."
