Nothing matters?
You matter! I realize that you are in for a tough fight, but don't give in. No matter what be willing to fight with all you have, in doing so you may be surprised by the result.
People can and people have beaten this, you just might be the latest example to do so.. but you have to be willing to give it your all.
I wish I could just give you a hug right now, but know that I'm at least giving you a virtual one.
