help with coping please.

Ta
I've struggled with depression and anxiety my whole life. I've also delt with self harm. All of this before Being sexually abused for three years...now that I'm out of that, I can't believe I let it go on for so long. Everything is getting worse and sometimes I don't think I can do it anymore...I wake up from the nightmares tearing into my wrists with my nails. Does anyone have any coping methods or anything that helps them? I'm really struggling...
