Jon, let me start off by saying how sorry I am that your going thru this.
Take care of yourself right now, eat, sleep, figure out a way to burn your emotions off as best you can. Be honest with yourself, your hurting, man, that's ok. Your only human. Don't try to be superman, don't be Sigmund Freud and try to figure it all out right now. There are no answers, so stop looking.
Time is your only friend right now. I don't need to tell you that going DARK not dim anymore is probably what YOU need to do for yourself right now. Don't let your emotions make your decisions right now please. Try to find out how you can just slow things down in your mind. Its gonna be hard to say the least.
Theres times I sure wish I could just put my phone number out there so someone could just TALK when they needed to. You've got a lot of people pulling for you Jon. Hang in there.
