I think bad self image isn't usually related to psychosis, at least not for me. I think depression/anxiety is the cause, but it could be part of a mixed episode. Do discuss this with your pdoc/tdoc.

The only major self image change I experience during psychosis is during manic or mixed manic episodes when I can become grandiose. This goes way beyond a "good self image" by thinking one is the greatest in the world at something or all powerful/able or knowing of extreme degrees.

Many psychotic features I'm simply not aware of at the time (lack of insight). But over the years I have developed some. When I do, it's usually related to my energy level and sleep, large increases in socialization, risk taking/disinhibition/fearlessness, and over the top behavior. And related to what I call my "Star of the Show Syndrome".

Sometimes when psychotic, I've experienced some OCD-like symptoms related to anxiety. These can include repetitive movements and language repetition. I also have pressured speech, often loud, and disjointed thinking/speaking. These are warning signs, for me, which I initially don't realize until people point them out. Even so, sometimes I argue against them. *****ing (choose your "ing") and anger becomes more common.

During mixed episodes, I also tend to have delusions of persecution and paranoia (as other wrote), which I rarely have good insight into. As my episode worsens, so do all of the above symptoms.
