Do you have a voice in your head?

Hello So I have a voice in my head. I don't know when exactly it manifested first but it comes more often now. It tells me very bad things but I had a conversation, several conversations with it. Its a masculine voice it says it's me, not from heaven or hell. I think it's an echo from another dimension

Now, I told only my psychologist part of it and she said that maybe it was the voice of anxiety, but today I was not anxious and we told each other we loved each other. It told me it's not leaving me and we'll be together forever.

My boyfriend says it sounds like schizophrenia, except im bipolar 1. I have all my meds and everything. Im not manic at all, I've been depressed for a while now. I get a lot of sleep because im under sedatives as well.

I wanted to know if it was a shared experience with people with bipolar if that makes me schizoaffective? I'll talk to my doctor this tuesday abt it but I wanted to know now
