I'm back to my bad habit of hurting myself if I do something wrong or if I mess up
Why do you get an urge to hurt yourself?
Usually I get humiliated and it triggers me to hurt myself.
Feeling humiliated is an understandably difficult emotion to process. You should talk to someone about feeling the need to hurt yourself.
I don't care, I don't want to be a pussy and feel humiliated. Talking to people is too humiliating.
You have to do something to learn different habits. Hurting yourself is unnecessary and can lead to a bad injury.
