I am glad you wrote me. Yes, there are ways you can stop from harming yourself.
First, understanding that cutting yourself is a way to express your deep pain and emotional distress. It feels that hurting yourself is the only choice because for a while, it makes you feel better. But the feeling only lasts a short time then you are back to where you were.
Second, take a look at your triggers. Why do you feel the need to cut? What are your feelings right now?
Third, find a new way to cope. List things you can do instead that you feel would help. Yelling into a pillow, crying, going out for coffee, calling up a friend, etc. Make a list and keep it where you can see it.
Fourth, develop support. You reached out to me which was a very healthy step. You want to stop, which is also good. Take the next step and have "backups" in case you feel you need to cut again. You can have one or two people you trust that you can call and confide in, or try a hotline. Talking to someone can make a big difference. Or find an on line forum where you feel comfortable. Sign on when you start feeling the need to cut. Talk it out.
Five, therapy. Talking this out will help you solidify new ways to handle your feelings.
All of your feelings are very normal. You just need to change how you handle your feelings so you can find healthier ways to cope.
