Help I keep grinding and pushing on my teeth! How can I stop?

I don’t know why but I have a weird habit of using my fingers and pushing on this one specific front tooth...I also grind my teeth. A LOT. I don’t even notice when I do it.

My dentist told me I’m wearing down my teeth...

Anyone else do this? What can I do to stop? Any advice? It bothers me so so much..Especially the pushing of my tooth...
