I am really sorry your family is dealing with addiction, it is so hard on the addict and the people who love them. My son is 17 and I have seen him twice in withdraw and it was not pretty. He screamed and yelled some really nasty things. While he never said he would kill us, I am sure he was feeling it. I did have fear when he was using and I would lock my bedroom door at night. I would wait to see how he is in a few weeks after the drugs have cleared. If you at all feel fearful, then do protect yourself and your family, but I think once the drugs are clear he will feel differently. Your son is safe and getting the help he needs, that is not wrong. Hugs, Julie
