Ow! I Cut my labia!

I was in my schools adiutorium and I went to step over a chair instead of going all the way around the row. I stood to far back on the chair and my foot caused the seat to fold up. My feet slipped and I fell lading with all my weight on my vagina straddling the back of the chair. I played it off like nothing happen even though it hurt so damn bad. On the inside I was screaming. I sat through the assembly. After it was over mostly all of the pain had gone. I went to the bathroom and there was blood on my underwear and pants. I tied my sweater around my waist and went to the nurse. I told her what happened and she sent me home. Luckily it was a half day and only about 40 mins left anyway. When I got home I jumped in the shower and hosed myself down. That did burn. I got a hand held mirror and try to figure out what I did to myself. I have large labia and one side looks pinched and the other has a big cut/rip on it and a tiny cut a bit below that. The cuts are on the inside of the labia. I put neosporin on with a qtip. The big cut is deep enough I could make the wound talk if I wanted to. (You know, by separating the sides of the cut and making a funny voice to amuse your friends, I cant be the only one thats done that)I am also using a pad to catch any bleeding. There doesn't seem to be much new bleeding. I don't think I need stitches because the way my big labia folds keeps the cut together. Any ideas how long this is going to take to heal? Is there anything else I should be doing?
