Found out today that my son is using heroin. I knew it was bad but this is way worse than I imagined. I feel like I've been hit by a bus, I literally feel like I can't breathe and my arms and legs feel like noodles. I actually saw him for the first time in 2 months. He looks so terrible and nasty. This is not my son. I am in such shock. I don't know what on earth to do. Please give me something more than taking care of myself and detaching. I love my son more than anything in this world.
