I would say call and go see a psychiatrist because ultimately they are the professional who can make a diagnosis. I mean, sure, one can "self-diagnose" depression because it's usually quite obvious, but other symptoms can occur in many disorders. When I first went in for evaluation, I had no idea what I had. I knew I was depressed. I knew I had had psychotic episodes. But things like mania/hypomania can often be confused with anxiety/panic attacks or whatever. People can become psychotic in any number of disorders.

The only way to know for sure is sit down and have a deep conversation/evaluation by a professional/professionals. My evaluation/diagnosis was no short visit. Plan on clearing your schedule for this and remember you have to be completely honest with the doctors evaluating you; no matter how embarrassing the symptoms (for example, hyersexuality) may be. My evaluation consisted of two evaluations: first by a psychologist then a psychiatrist. They asked me if I was okay with trying psych meds. Truthfully, nobody can force you to take medication. I voluntarily began taking medication because I didn't know what else would help. And though it has helped me, it has also robbed me of some of my personality (or so it feels).

I wish you luck in your journey. It may be long, but it will be for the best. Medication or not, it can be a relief to finally get that diagnosis and from there, the proper form of treatment (for you) can truly begin.
