If you think you have even mild schizophrenia, go see a psychologist and get assessed. Because if you do have it, and you don't do anything to treat it, you could get to a point where there's no going back.

I watched a friend of mine decline like this and over the course of about a year he went from being fairly normal, to being generally paranoid, to being so paranoid that he though people at work were speaking in a secret code about him, to having full blown delusions that the govt was after him and bugged his apartment, to then having full blown hallucinations that divine beings were speaking to him. He got to the point where he was so psycho to be around that even his own family had to kick him out in order to save their sanity. They tried everything to get him treatment but he was too far gone and would refuse treatment because the "angels" in his head told him that the treatment was actually malicious. Today nobody really knows where he is. He could be dead or he could be a hobo on the street somewhere.

If you think that could be you then get some help ASAP and don't let it get to that point.
