welcome, upsidedown. i'm sorry to hear about your daughter's addiction. it is a difficult disease, i understand. my daughter is 22 and was a handful of days from six months clean and sober from alcohol and cocaine abuse, when she relapsed last week. as parents, the fear is painful, very painful.
there are many folks at my alanon meetings who deal with drug addictions, as well as alcohol - if you don't feel you have enough meeting options. my husband and i also do some private counseling, and that also helps us very much.
remember this about your daughter's addiction - you didn't cause it, you can't cure it, and you cannot control it.
keep posting your feelings and educating yourself. meanwhile, i'll pray for your family.
recovery is possible, k
