Hi Sunnee, I can tell you without a doubt and 110% positivity that there is NO link between Schizophrenia and depression.
Doctors dont know how some people get Schizophrenia but some schizophrenics are treated for depression as this tends to be as symptom once mania is controlled.
So just because you have Depression does not mean that you will have or get Schizophrenia.
BTW, I like your sig...
