For 7 years have watched/ supported my son as he smoked heroin . For the last 4 years has been on methadone detox at home and then sent him to residential rehab . Been x2 there and just found out relapsed again . Agreed at last rehab counselling session that if happened again not to give money or send again . Am exhausted by it now but terrified of him becoming homeless / dying . Anyone any advice on how to cope when need to withdraw from loved one
