I think you explained it all very well, and I would say it is possible that you have some form of psychosis (you have to have psychosis for 6 months for schizophrenia) but don't worry there are great medications and therapeutic techniques that could help you especially being so young they might even be able to stop schizophrenia from developing with early treatment---ie a low dose of meds with therapy. None of us are professionals in diagnosis here though so please do seek help from your therapist.
