do i have schizophrenia too?

Hello, I'm a 20 year old guy that is currently diagnosed with bipolar and anxiety. That's been for about 2 years now and I have been off medication for about 5 months. Well I've been doing research on schizophrenia lately because I've been quite concerned for myself. Now, I don't get full blown hallucinations, but I do get, what I call, shadow people. They're just dark figures following me basically. Sometimes they're in my car, most of the time in my house, on the stairs watching me. but I know they're not really there. They're just dark shadowy figures, that have 'character'. I also tend to talk to myself very often, I also argue with myself, and every decision I make has to be consulted with myself. It's not like I'm talking to another person, more like, I'm talking to another me. I have racing thoughts out the ass. And I sometimes have really demented scary thoughts, but I just tend to push those aside. I have a very vivid imagination. I can literallysee things in front of me by just imagining it. Like I don't actually see it but it's very vivid. It's hard to explain, sorry. When I'm in manic state I tend to think I'm special or super human in some way. Buy I've gotten used to that. And to me some of the things are more logical now than what they were before. I'm almost always anxious. I'm anxious right now. I think most people hate me. Most people are trying to hurt, steal, lie, anything bad to me. I know, it sounds very self centered but I can't help it. (I.e. right now I feel like most people will brush this off as another lying little kid crying for attention, I mean, I don't know) I collect receipts, all of them. I don't really even know why. But I know I might need them. I don't know what's wrong with me. Please help.
