Always do, every single day. Came close to doing it in December last year, but backed out at the last second because I'm a coward. I was in the process of running my car into a light pole at top speed without my seatbelt, but after hitting 90kph (56 miles for those of you on the Imperial system) I couldn't go any further.
My life has been miserable for the last three years, slowly spiraling further and further down hill. My problem is so bad that it haunts me everywhere I go; when I'm out shopping, waiting for the train, driving my car, walking to University, talking to friends, spending time with the family, eating lunch, you get the idea.
I used to be happy, every day was another sweet marshmallow out of a never ending bag, but that eventually stopped. I hate life now. Every time I experience something uplifting, it's torn away from me in the manner of one step forward, two giant leaps back. I've prepared though. If I go for another attempt I've told my friends about last time so they're prepared for it.
They want me to get help, but I'm beyond that point now. You on the other hand should, you don't want to end up like me. I would never wish my life on another person, not even my worst enemies.
