If this story is true, then I'm sorry that this happened to you. I can understand addiction cause I had a similar issue. After the military I smoked marijuana heavily and it took over my life. I eventually went to an addictions therapist at the veterans affairs and it helped me a great deal. I went through such a horrible depression and anxiety and the only thing that made me happy was smoking, eventually it became the only thing I wanted to do every single day. I know how that feels and I strongly suggest you get some help from an addictions therapist. It will take time but you can have your life back, and hopefully have you're family again, good luck man
