Wow do I feel elderly after seeing the young age range for this topic. Let's just say, I'm over 50, I've been in the abyss for literally half a century.
My black hole was spinning at 5 years old. One of the reasons I'm still unfortunately here is, that I've used the possibility of suicide as a tool to trek on.
I always knew how, and kept ways to ctb, but safely tucked in my room, I could've ctb decades ago.
Even thinking about ctb soothes me in my worst times. I've been hanging in for my family, and my loyal dog, while I keep my eye out for something that may change my outlook. Peace and light to all.
