i am sorry this has happened to your son & to you too. as a mom i know how u feel. it happens & it is up to them to get back on track.you are powerless. my son too is bipolar. there are a few on here that there addict children are bipolar. it is not your fault that he relapsed.if you had gotten up & called him it does not mean that he would not have relapsed.he may not have answered the phone.do not blame yourself or the genes.i have only 1 addict child out of 3.it is choices in life that they make. take care of yourself & leave him to your H.P.
