Do you think that self-harm is addictive? If so, have you replaced it with something else?

Hello, Im a psychology student and Im currently working on my bachelor thesis which focuses on self-harm and it's addictive nature. I would love to hear from you guys. Do you think it's addictive? Have you managed to get rid of that addiction? Have you replaced it with something else? And is there something you would like to say to professionals in the mental health community?
