I understand your feelings. I have begun to detach andmy son text me this weekend and I replied for the first time(on a borrowed phone). I miss what might have been and my baby boy. He is gone, snuffed out by years of abuse and drug use. I pray my son will come around but I am starting to live for myself. He is living on the streets. He has a court date soon. He may spend some time in jail for not being there. I am not going to try to fix it.
Anywho, good luck with your son. As long as there is life there is hope. Take care of you for a change.
Hugs!
