Struggling with Self-Harm Urges

i used to cut a few years ago, and after a traumatic event related to the self-harm, i abruptly stopped. it's constantly been on my mind since then, but i managed to blocked out the urges for a while mainly out of fear. to... my own dismay, it's come back this year. i started cutting again, and it's more frequent and more painful this time around. my mental health kept getting worse and worse this year so i finally decided to start seeking some professional help, but i'm not sure it'll work. i don't want to go through the same kind of traumatic event again but it's so, so hard not to cut. i've lost every battle against the urge to cut this year and it makes me want to cry.
