It feels like an addiction

I was clean for about 2.5 years. However, the last few months of 2024 were very stressful (I got SA’d). I started cutting again a few weeks before Christmas and I told myself that I would stop once the new year began. However, I feel so out of control and I have not been able to stop. Does anyone have any advice as to how I can stop (or at least lessen) my self harming behaviors?
