I hope you're asleep right now and dreaming peacefully. Just wanted to say that I'm worried and thinking about you too
Please don't choose a way out when there's certain to be a way through. As others have suggested, if you feel an urge, call a crisis line. Talk about anything and everything under the sun (even if it's complete gibberish) for as long as it takes for the feeling to subside. That's what they are there for - to save your life.
I hope you are feeling better when you wake up.
