I cannot believe how stupid I am. After getting angry with myself for the thousandth time in what seems like several months in a row, I thoughtlessly picked up the knife next to my computer and attacked my hand.

Several stitches later, I don't know what to do.  Nobody but me knows what happened.  I have insurance but I don't expect this will be cheap.  I cannot believe how stupid and thoughtless and worthless I am.  I was just wasting the time and energy of everybody working at the ER.  I don't know what to do now.  I don't know how I can tell anybody, or how I can explain this to my partner, who is not here at the moment.  I don't know if I *can* tell anybody.  I just want to go to bed and sleep for a long time, but the stitches will be there when I wake up.
