I had a past of self harm when I was depressed but now everything is fine and I am happy with my life. I keep thinking about self harming. How will it stop?

Thank you for being honest with us, I really appreciate it. First of all, I want to validate how proud I am of you for taking steps to move on from such a difficult and painful time in your life. I wish I could give you a more quick-fix answer, but as you probably know, recovery isn't usually like that. One thing I would suggest would be talking more to a professional about helping to identify your self harm triggers. Are there some situations that still affect you during happy times? in noticing those, you can figure out positive coping mechanisms to turn to and keep yourself safe. Please reach out if you want support.
