Hi my daughter has been taking herion for over 20 years .
I have support her and tried to get her off this devil drug I can no longer
do this anymore and like your son she is homleless too.
There is no answer to this ,I have cried so much over the last 20 years even had a meltdown.
I just want peace the life style they choice is so chaotic and that has been my life to . Like youI have let go most people dont understand this but they have not lived with a drug addict .
I hope you can have peace in your life and maybe one day our children will turn their lifes around.
