Yup. My dx often switches between schizoaffective and bipolar. You're definitely not alone; there are plenty of others here that struggle with psychosis. I'm on a medium dose of clozapine, an antipsychotic that's generally for the treatment resistant. Ive been on high doses of other antipsychotics though, but they didn't help as much.
One thing about meds is that its pretty important to take them regularly as prescribed otherwise its hard for them to work they way they should. I hope your mania and psychosis goes away soon without causing much damage.
