Darrell Hammond, most known as the best Bill Clinton impersonator from SNL has written a harrowing book regarding his self inflicted abuse before and after SNL.
I know Mr. Hammond's is more extreme, but I can relate on his mother's emasculation of him,and the cutting.
I did something worse than cutting. I use to use my thumb nail to just etch away those seven layers of skin. And I would make it look like suicide scars on my wrists. This is his fresh air interview. Terry Gross was so coolto him.
