I see shit >:3

So i shouldn't be making it out as some sort of joke but i have been developing a type of disorder in which i see or hallucinate things that aren't there but my mind thinks it is (Schizophrenia for short) and i have been scared to tell people as there was a boy at my school who had schizophrenia and had been taken out of school to a mental hospital, i had already been to a mental hospital for some previous antics i have been inducing and it was one of the most shit places i had been to, i would really like to not go there again so what exactly should I do as some days i have it some i do not.
