Dude...when you say you know you need to talk it out, I seriously want you to do that WITH someone. And soon! Someone at church, at the hospital, someone face-to-face.
Worst thing in the world when you're facing a bout of depression is to allow only YOUR mind to talk to you. You keep replaying the same negative thoughts over and over and it is NOT healthy. I know -- been there, done that. I know it's possible to get past it.
It doesn't matter how bad things get financially, romantically, professionally, or whatever. It ALL gets better eventually and you look back on times like last night and say, "Wow...I would have missed out on these good times now if I'd gone through with it."
And God knows I know the pain of self-hatred. It had nothing to do with my sexuality (which is often the case in many teen suicides). It was all the crap and humiliation that my mom beat into my system, both physically and verbally, since I was a kid. But, 19 years ago - July 11, 1985

-- that attitude inside me changed and all the negativity got washed out of my system, thanks to a great church group in Starkville, MS. I know just how worthless, desperate, and hopeless one can feel when they're at the brink of suicide. And you don't feel worthy of God's love...or anyone's. But you don't have to change ANYTHING for Him to come into your heart. HE changes YOU.
There will always be trials in your life (been going through one this past week). No one can promise you a big beautiful rose garden. But once you've been to the bottom and you're able to climb back out again, you gain that resolve, strength, and determination, along with a whole new outlook on life and your future, that helps you make it through the next one...and the next one...and the next one.
Matt, I'm praying my heart out for you. Please go be with someone and talk with someone. Don't stay inside and keep all your thoughts between your ears. Let it out, get it out, scream it out. And check back in when you can and let us know how things are.
