Hi friend,
Your first step was great because you identify the problem and you do not want to get into addiction again. Usually the person who supports his/her belief maintains recovery process and prevent relapse and that should be under the supervision of your psychiatrist. The period of the treatment should be ended in stable situations and conditions (maintenance step). `My point of view is keep visiting your psychiatrist, and you may discuss with him the group therapy done at different hospitals in some areas for post -partum to avoid anxiety beside the prescription.Love to share my opinion with great people as you!
