I've had most of these issues. I'm inclined to agree with KUREHA about school conselors, school conselors know and understand nothing, thus they cannot be trusted, however you may have to tell them stuff just to get referred to a psychologist. I know it's hard to trust any of them, especially when medication options get brought up. I think it would be worthwhile to try medication, it has helped me a lot, like you I ruled out schizophrenia because I didn't think I was hallucinating, I hadn't even told my doctors about it. During a change in meds (for OCD, Depression, and Panic Disorder) the hallucinations went away, that's when I realized they weren't normal. You'll still struggle on meds and with therapy, but it can make life and school much more manageable.
