I self-harm unconsciously, how can I break this habit?

When I struggled with this issue, I found it helpful to keep my hands busy doing something productive like painting, drawing, taking photographs, even writing was a good way to relieve the urge to self-harm for me. One of my dearest friends, whenever he feels the urge to self-harm, he will go for a run, running sometimes 4 miles until the urge finally passed.

Call the suicide hotline immediately. I'm sure that their service will give you good care as soon as possible.

Try focusing on something else you could do with your time. You could paint, keep a journal or even draw on yourself instead of cutting.

Breaking a habit of self harm is difficult. But not impossible. There has been lots of proven ways to stop self harm and be able to help. Some of these things could be such as writing down how you feel. Ripping up paper. Drawing on yourself where you would normally cut. Or making a paper chain and adding colourful paper for one you haven’t self harmed that day and using white or black when you have. This way you may see an improvement throughout a course of time

Habits are an easy thing to develop, but a hard thing to break! I am glad you are aware it is happening unconsciously, but that would be difficult to deal with. I think there are some factors that would play into breaking the habit. First, it does take about 30 days of not doing the habit to break it. It also depends on what type of self-harm you are doing. I think maybe something like journaling might help get the the bottom of why and when it happens (triggers, ect.). Also, maybe try something like distraction to help break it. I hope you find what works for you!
