First of all, well done for reaching out for help with self-harming. I know it won't have been easy for you and it's a really hard thing to do, so you've made a really good first step.
It is incredibly daunting to think about giving up a coping mechanism that you've used for so long, but it is possible. I used to self-harm and for over eleven years that was my go to response from anything that happened. Now though, I can say I'm free from it and I am so glad I took the jump into looking for something healthier.
It might be helpful to talk about what makes you self-harm, i.e. what are you triggers and your emotions you feel when you do it. Identifying triggers can help you avoid such circumstances in the future and allow you have healthier coping mechanisms in place for if the situation does arise again.
It might also help to take a look at the RYL Big Distraction List
to use when the urges hit and the RYL Alternatives to Self-Harm List
to see if you can replace self-harm with healthier ways of releasing pent up emotions.
Lastly, welcome to RYL :)
