Question about Delusion

I don't know if this is in the right place but I have wanted to ask about this for a long time. I have been diagnosed with Bipolar 1 with psychotic mania. When I am manic, I have delusions that I become a famous person and genuinely believe I am this person, sometimes for months at a time, but they are dead in real life. Before I experience this, I often experience him talking to me with a voice in my head (not from the outside but within my head). When I'm unmedicated I also experience sensory hallucinations, thought insertion, "radio waves in my head" etc. I have gotten quite good at managing these sensory hallucinations but my executive functioning is still greatly impacted while having episodes. This side of myself has gotten better about not getting into trouble but I was wondering if there was research and case studies I could research on this phenomenon to better understand my experiences.

I did try medication but it stopped working after some months with regards to the voice/these episodes, although they did help with my mood issues and some other hallucinations I was experiencing. I couldn't afford healthcare so I haven't been medicated for a while but I am doing alright for now.
