Razor cut myself suicide 15 young

I’m only 15. I have job at my moms store, I’m a freshman in high school.
My mom never lets me out anymore. All I ever do is work and go to school. And at school I am made fun of. I never act like I care. But once i get home from work I open a pack of razors and tear my flesh.
The other day, I thought I had had enough. So I applied more pressure to the razor. I bled for only two hours
