Psychosis is not a part of OCD.

Are you sure that what you are experiencing are hallucinations and delusions?

If what you are experiencing is part of your OCD, most likely you will know that these things are irrational. That's the thing about any anxiety disorder-- no matter how scary or real the thoughts are, one can ultimately differentiate rational from irrational.

Schizoaffective disorder includes the mood swings similar to bipolar disorder. Do you have depressive and manic episodes?

I'm sorry you have to deal with all this confusion and these labels.
