Generally you get a diagnosis from a psychiatrist. If your depression is not situational, than it is a chemical imbalance. It could take therapy even to distinguish this. Over time, I mean. But usually a good psychiatrist can tell you what is going on.
I would suggest that you talk to your doctor about
seeing a psychologist or therapist. Or even talk to the doctor themselves about
the way that you feel. That is the best place to get started. From there they generally recommend a psychologist or a psychiatrist.
Good luck to you. I hope that you figure out what is going on.
Best wishes, and keep posting.
