I haven't cut yet, but, I really want to. If i get scared, anxious, embarrassed,depressed, angry or other things.

I am getting such strong urges, I was going to cut, but I couldn't find anything. I really want to cut, & the urges are not helping. There were raor blades in my art class, & I was so tempted to crap one, & cut myself right there, in the room...with everyone there.
