Has it gone to far already ?

I don't consider what I am doing to be self harm I mean I am hurting myself but not really badly . I take a shaving razor with three blades and I cut my upper vagina area its more like shaving the skin off which means like reall little cuts they bleed for maybe five to ten minutes but that's it . I don't know if I can stop it's become my life already and I have only been doing it for five months .my mom knows that I cut but she doesn't make me stop because they aren't really deep.Will they admit me to the hospital (my doctors) if I don't stop? And are metal hospitals really like that book impulse by ellen Hopkins?
