I self-harmed today after 2 years clean
What made you hurt yourself?
I can't deal with my friend's cancer so I needed to hurt myself.
If you are having a mental crisis you should talk to a professional. Having a lapse and harming yourself is nothing to be ashamed of, but you should reach out before the situation gets worse.
It was a mistake. It won't happen again.
I am glad to hear you say it won't happen again, but you still might want to talk to someone. Self-harm is a serious thing and a mental health professional can help you through it.
