Hey there, montimoo. I'm sorry to hear about the state you're in right now. Being drunk and high isn't much fun when crushing reality is also attending the party. I don't imagine you're in for much of a good time.
You're not a loser, though. Especially not for being afraid to ctb. Survival Instinct is a thing. It's really, really strong, and you just don't get to have any control over it. Not being able to get past it doesn't make you a loser, or a coward, or any other deprecating term you could name. It just makes you human, someone with an evolved drive that is really damn good at keeping us alive, whether we want it or not.
But I get it. Things must be pretty awful for you right now, if you're in the state you're in just trying to escape from it a little while. All the same, don't beat yourself up along the way. The rest of the world is more than happy enough to do that without you getting involved.
