Terrifyingly close to the edge

I am so stressed out and emotionally in ruins I'm beyond physically uncomfortable. I don't even know how to describe it it's like I'm being eaten alive. My body, heart, mind and soul feel foreign to me. This is not me. I am so terrifyingly close to the edge of being lost in the dark hole of drugs it scares me. All I want to do is go get high to take it all away because nothing else is helping and I can't stand this feeling any longer. I just want to feel better. I haven't felt like this in 8+ years. I know I'm strong, I've been through a lifetime of things most people never experience but I think I'm just about broken. I'm terrifyingly close to the edge and all I can do is pray that I don't jump....
