As many have said, you did the right thing. It was one of the hardest things I ever had to do, tell my son he can't live here and drop him off at the homeless shelter. But you are not alone!!!! Just knowing that gave me great peace. I have personally gotten a lot out of alanon. It's made me a better person overall, not just in my dealings with my son. I also found a local support group for parents of addicts and they are an amazing support. Read books, if that's your thing and share, share, share. Sharing about our struggle (cause hes's not the only one struggling here, it's affected the whole family) was freeing for me. *hugs*
