I've had mh difficulties on and off all my life. My most recent episode included psychotic symptoms, although I've never been admitted, fortunately.
I've seen a new psych a couple of times and he has changed my diagnosis to bipolar (sub clinical as I don't get grandiose/ no admissions) with emotionally unstable personality traits.
I'm on meds already, an antipsychotic which also acts as mood stabiliser and anti depressant. Reading up on bipolar, I'd say I've probably had mixed episodes in the past as I have bags of energy, insomnia, racing thoughts etc coupled with suicidal ideation. When I'm very low I have psychotic symptoms also.
Ironically, I've received this diagnosis at a time when I'm well, so it's really hard to accept. However, if I stop my meds again I know I'll relapse. It's a bit shit really.
