I'm not ashamed to say that I used to self-harm.
What caused you to self-harm?
I was sad a lot of the time
There's no reason to be ashamed, but I'm glad you stopped self-harming. It takes a lot of effort and strength to do so.
It was really hard to stop because I liked the way it felt.
I understand that it was difficult, and I'm really proud of you for stopping. It can be hard to stop doing something that makes you feel good even though you know it's bad for you.
