TW self harm

I’m 17 now and about to graduate high school and I’ve been cutting for a few years a stopped for a little less than a year and now I’m starting back. It started as little things but it’s slowly getting worse and worse and I’m really worried. I don’t know what to do I can’t tell my parents or friends. And I’m most scared about my boyfriend finding out. It’s all stemming from my mom and the way she’s been acting towards me recently I just really need help.
