Can a woman, my sister, who had only one schizophrenic episode due to marijuana abuse (early 20s) accompained by a suicide attempt and diagnose of bipolar when discharged from psychiatric hospital, lead a normal life without any treatment AT ALL since? She suffed childhood traumas, today 35 years old has always been dificult to relate emotionally unstable and accumulated several conflicted personal relationships in all aspects of her life. How likely is that a second episode will happen? She does not accept psycological help and distance herself when family try to help. Any advice for family members?
