Is this a form of self harm?

I had acrylic nails and I had one left. It wasn't loose but I started picking the ends of it to lift it. I kept pulling it until it came off. Like I would pull it a it then stop then pull it more until it eventually came off. It even ripped the top part of my nail off. Even though it hurt as I was pulling I still wanted it off. It's like I wanted to feel pain. Also today in the shower I put my arm under the hot water for like 2 seconds on purpose. I do suffer from anxiety, depression and ocd.
