Yes cr,
My son was missing for alot longer than usual, not long before he went to jail. I was getting scared as it was so unlike him. I called all of those places that you called. It turned out that he had moved in with someone that he knew I would be totally against him being with, way way out in the country where no one knew where he was. He was hiding from The Law too. He was fine, except his usual drug addiction. He was arrested is how I found out where he was.
Try not to worry too much. I always had to tell myself, "Just remember all of the times that he was gone before, when you were hysterically worried and he came home and acted like nothing ever happened and when you said something about how worried you were, he treated you like you were pathetic."
