Hi and welcome!
I am a mother of a 24 yo daughter who has been in/out of rehabs, sober homes etc for almost 7 years. This place will truly save your sanity. The best thing for me was knowing I was not alone and other "good" parents have kids in trouble. I have made some amazin friends here who have cried, prayed and laughed with me.
Come back, keep posting and read!! Lots of good folks who truly care.
prayers for you and your son,
susan
