Honestly, if your symptoms are apparent, a psychiatrist might diagnose you pretty immediately.

Doesn't make it free, of course, but it does mean you wouldn't need regular sessions.

I was seeing a psychiatrist for a while, stopped for unrelated reasons, and now my med manager or primary doctor writes the prescriptions for my meds. I see a doctor once every 6 months, basically.

Now, I do have insurance, but for a minute I didn't, and a visit cost about 200$, can't remember exactly.

200$ every 6 months is fairly doable.

Good luck, though.
