I wish there were some way for me to let you all know,
To say "Good Bye" should I decide to 'exit' early.

I totally understand, but sincerely hope that is not the decision you make. I know that someone in my family would post something on my FB page to announce my demise, and that someone would spread the word here. I am so sorry that you feel that things are that hopeless. What can I do to help?
