Just the fact that I'm alive. There's times I feel otherwise, but as you said, the things we go through just assures us that we're still alive. While given this life, I'm grateful that it's in the current state that it's in since there's people who have it so much worse in so many aspects, so it's selfish to want more than what's here. I still can recall certain memories that seemed like a slap in the face that I've said from what is the complete opposite than this.
I'm grateful for the people I've came in contact while being here. Some that honestly helped for me to stay as long as I have since there was a point I felt there was no reason despite how I kept saying I wanted to leave. Next thing you know, there's people who made me glad I've stuck around and made me feel less alone. So the credit where it's due is with many of the people here for simply sharing what they've shared. Also it has helped me to have the interest to want to believe again. I know the rest is up to me and what I decide to do, but if I never visited a site like this then I don't think it would've happened. The power of prayer seems to have been proven from here alone. So I want to thank the community for that.
There's plenty of other things, I'm sure. I think what's already listed says enough.
