Karen, I am so terribly sorry for your loss. You know you and your family are in my prayers. Yes, it is devastating. The loss of any young person is just so wrong. If you need us we will be here, if you need to be by yourself or w/ your family, do that. This is the part of 'virtual' that bothers me, I wish I could give you a hug. I will send it along to you, along w/ my prayers.
Sometimes the only way to look at this is he is out of his pain and he's w/ his mother. My cousin's son did this a few yrs. ago and my cousin (my Partner in Crime) was so rocked by this. While trying to find something to hold on to, she said, At least he is out of his pain.
Again , I'm so sorry - you have my deepest sympathy.
God bless. Alice.
