The same reason men get into self harm? The same reasons we're all on this site?? Why are you pointing out women specifically?
Because facts matter. Because biology is real. Because men and women are different, and react differently to things, and take different courses of action to things:
And a fifth of young adults have self-harmed

Men's self-harm tends to be drugs, hard alcohol. Women tend to cut or have EDs. This is a generalization of course.
Also, I am not on this site because I want to self-harm in the sense of "cutting myself for release". The self-harmers here - both men and women - are probably in the minority here, but of those who do it, I would guess that it would be mostly women:
Adolescents who harmed themselves had a risk 17 times greater for suicide and 34 times greater for drug or alcohol overdose at a young age, compared to their peers who didn't self-harm.

I was pointing out women specifically because I made the assumption that the OP was a woman. If I am wrong, let me know so I can apologize.
