I am 21 and have severe anxiety and depression issues, should i be worried about schitzophrenia?

I read that schizophrenia typically is diagnosed to people in between the ages of 20 and 25, who have previously had an onset of other mental health issues such as anxiety and depression. I have both of these to a large degree sometimes and I do tend to withdraw from society which is apparently another connection to schizophrenia. I am a little worried about my vulnerability for schizophrenia. Should I be?
