I recently started doing self-harm. Is that bad?
Did anything cause you to start practicing this?
No particular reason. I just thought it would be a nice way to release stress.
That's a bad way to try and relieve stress.  There are many healthier ways to do so than by hurting yourself!  Try finding a new hobby!
Self-harm is the new way to release stress and I'm not going to stop just because you don't like it.
It's not a new way, it's a harmful way. Why would you want to do that to yourself when there are better options? Self harm will only do damage to your body and the stress never goes away.
