First time posting on this forum. Been diagnosed for about a year now but was given an OCD with psychotic features diagnosis at 14.

Is it normal to feel constant fatigue? And I mean constant in the truest sense. I'm only taking Lithium (300mg x2) and I can't seem to shake this crap. I'm not even sure it's from the Lithium. I couldn't even take it this morning because I had my blood drawn and I feel like this has been one of the worst moments.
