My ctb date is tomorrow morning at 3 a.m. Hopefully, I can go through with it because I think I'm ready. Also, I completely understand how you feel. There were so many times I backed out of my attempts because of the fear of death and the unknown of what comes after. I'd always end up feeling so upset with myself, thinking I was a coward, especially knowing that so many others could do it without hesitation. Recently, though, I've come to accept that no one, including me, really knows what happens after death: we won't truly know until it happens. That said, I think it's finally my time to end it all. Everything in my life has gone wrong, and this feels like my only sense of escape. If I do go through with it, I wish you the best of luck.
I hope you find the peace you're searching for, whether it comes through life or death :)
