Stabilised symptoms and conditions

weight gain started almost immediately i gained 20 kgs during both pregnancies on zoloft. Although my anxiety/panic and outbursts of uncontrollable anger, and irrational thought patterns all stabilized remarkably on zoloft I have NO interest in sex, and uncontrollable urge to drink alcohol and I cannot stop until i pass out. Also, void of emotion ...haven't cried in years despite traumatic events that have included the deaths of grandparents, a divorce in the family and a miscarriage. Each time I try to go off this stuff I end up experiencing amplified symptoms of my original problems as well as severe depression and paranoia so I get scared and go back on it.
