( ok this is kinda the God/ Devil version on this subject. i dont know if i am right or wrong and im sorry to offend anyone who doesnt believe in God or the Devil. )
Schizophrenia is when a demon or evil spirit enters your body and makes you think there are things or people there that arent there. or from what ive heard its where you have more than 1 personality. u and that demon(s). for example there is personality 1 and personality 2 if personality 1 is in control personality 2 doesnt know what personality 1 is doing so when personality 1 finaly takes over again it doesnt remember what personality 2 has done. a schitzo can have more than one personality or demon possesing their body. it all depends on what happens. this is only what i have heard i am not sure if this is tru or if its a bunch of bull shizz but i, personally, believe that. but i also believe in God Devil demons and possesion all that stuff. haha hope that you find out what u wanted to know. (silent im really sorry about your mother, i hope she gets better sum day

and pigsrcute2 im sorry about your son. i hope he gets better one day to. )
