I don't think a regular doc will do much for you. All they know how to do is match drugs to symptoms. If you want medication, which I don't think is called for yet, see a psychiatrist. If you want to talk it out, see a psychologist. They're the experts in this, but your regular doc will be more than happy to take your money even when things are out of their area of expertise.
Tell your doctor exactly how you have been feeling, don't leave anything out so she or he can give you the help you need. Trust me, the pain you are feeling is temporary. It will go away and you will have better days. I promise. So get the help you need, and maybe pills will help your moods and counseling and getting everything out.
What is the outcome you are hoping for by telling your dr? Are you missing support at this time in your life? How long has this depression been going on?
