At the age of 19 your brain is not quite fully developed so I'm hopeful you will improve. It sounds like you are going through a psychotic episode, so I wouldn't label yourself schizophrenic just yet as you're likely to come out of it and lead for all intents and purposes a normal life. You are right about taking things one stage at a time and try to recognise what triggers your moods - and rest! I have a family member who is schizophrenic so know what a prison it can become if not addressed. I wonder whether some other kind of counselling might work better rather than a formal psychiatrist.
