I don't think I will be able to stop cutting, any suggestions?

I've been going to a therapist for a few months and she helped for a bit but i started again. I am honest with her. I tried the rubber band but i did it so much my whole wrist swells up and it just isn't enough. I'm on zoloft (100mg) and i was on lexapro but that didn't work. I tried ice on the wrist but that doesnt work. I always try to get rid of all sharp objects but then I find something again and just start cutting without even realizing or mindlessly taking the object home. No suicidal thoguhts, I used to have them. not anymore. I just don't feel anything and I have adrenaline rushes. help? /:
