I don’t know what’s wrong with me.

I have a little person in my head not literally but also like yeah literally. It argues with me. And again literally but also not. I don’t know if I have paranoia or anxiety. My mom is legit crazy so I’m sure I could have whatever. I try not to let it get to me but its getting so bad. My husband can’t leave the room without my mind going straight to “he’s going in there to sext his girlfriend” he doesn’t have one btw. I also seem to think my father in law is going to do something to my daughter and in my mind I know none of this is true but this person argues. I know I need help but I don’t know where to start. UPDATE I JUST WANT TO MAKE IT CLEAR I KNOW ITS NOT A REAL TINY PERSON. That’s just the best way I can describe it. Like people with eating disorders say they have a monster or voice it’s the same thing. I know it’s not a real being.
