never ending sadness

It never ever fails for me to go a day without having an outbreak of feeling depressed and suicidal. Today it happened while i was driving and i got the worst road rage ever, then i got home and cut myself 4 times deep enough, but not deep enough to actually feel better. i want to die, i hate my life and i hate that i can not handle anything, maybe i am too sensitive to be alive. But hopefully one day i cut myself deep enough to hit a vein and end all this pain.
