Should I have hope?

So...it has been awhile since my last post. There has been chaos, chaos, and more chaos! But I guess that is what drug addicts stir up. My son moved back home briefly after his relationship with his girlfriend ended. His behavior was so crazy, I thought I would become physically ill or go crazy myself. We should know better, but tried to give him an opportunity to get on his feet. However he chose to dig a deeper hole. I don't think he realizes how bizarre he is on drugs. He has been very deceitful...lying about anything and everything, stealing anything he can, and probably much more that I don't think I even want to know. Anyway he eventually was asked to leave our home. He was homeless for a few weeks. Ouch! Now doesn't that break a parents heart. Most difficult thing I have ever had to do....also very nice to live without his sickness. That feels a little selfish to me to say that. I started attending Alanon meetings (they don't have naranon where I live). From the very first meeting I learned I do have a right to my own life even if he chooses to remain an active drug addict. It has truly helped me to feel better. Not to say that I don't still have sad times of wishing his life didn't ever take this path. But I have mustered a little strength here and there. So thanks to whoever suggested Alanon. I have to disconnect from him and let him go. About the same time I began to let go of him, he decided to check himself into a rehab. Maybe there is hope.......
