Update on my son
I talked to him today and he sounds so much better. He said he wasn't trying to be mean when he said to leave a message for him at times. He said he was just focused on the groups and other stuff. No one thought it was mean, we knew he was working. He had a reaction with a medication the doctor said, which was part of the problem so they tweaked it. He said he was craving fish. I will definitely make him some. But he said he was opening up to therapy. I told him I was so proud of him. He said he wants a new bed. It's definitely a work in progress but there is progress. And talking about it with people that can relate helps. We're going in the right direction. Hopefully the botox works too. I'll know more tomorrow from his evaluation.

...like a bad situation is starting to transform into something good and productive. A good support system can mean a world of difference for someone in your son's shoes. It sounds like you are definitely there for him. I've been hospitalized a few times. I would get locked into this interior nightmarish state seemingly unable to communicate my true feelings to anyone. I was able to break this terrible silence due to the love of my mother. She was the one person who I trusted enough to be able to open up, and that led to me being able to get the help that I needed.
The love of a mother or a father can break down those terrible barriers, or at least it allows the parent to take appropriate action when a serious problem arises. I know you said your son contacted someone else when he felt like he was getting close to the end, but he will remember how you have responded for him in this time of crisis, and hopefully understand that you are always on his side.
I thought no one cared about me. In fact, I thought the opposite was true...that everyone wanted me to die. I found out when I opened up to my mother about my distress just how many people truly care about me. It was a whole lot more than zero. 
Best wishes for both of you
