Hi thanks for your message.
Nothing triggered it as far as I know. I get these impulsive ideas and can't focus on anything until I do whatever the idea is. This time it was hurt myself. A few days before it was cut my hair so I cut about 7inches off lol.
I quite know the feeling, I myself relapsed a few weeks ago pretty badly. One question if you don't mind my asking, have you or do you want to clean and wrap your injuries? They, especially the ones on your hand, could get infected and cause a lot more pain.
I cannot say I know exactly everything you're going through but I do also deal with self harm, as well as not always knowing what triggered them. Like someone already said, I'm glad you're able to talk about it and let us know, it's always a weight off your chest (at least for me) when you're able to tell someone.
