my daughter has been to rehab 5 times. she is 21. the only way i allowed her to live with me is by her aggreeing to sign a sobriety contract, this will be the second time she broke it. the first time she aggreed to go back to rehab when i found out she had relapsed..... this time she chooses to leave and not go to rehab, to be homeless and be a heroin addict this is her choice.... i know there is nothing i can do, but it is hard to let her walk out the door and be a heroin addict....my question is am i doing the right thing? i know the answer is yes, but it hurts.
