I guess a Stanley knife isn't sharp enough.

I decided tonight to go to my main artery in my wrist, cause it all just bacame too much. So I slit my rist vertically. The blood started running and I went to sit is a warm shower, not long after that the blood stopped FK why!!. I thought, I can't even get it right to pass myself on to the other side??? How am I supposed to succeed in this life!
