Is titling my youtube video essay good damage getting me a copyright?

I, want to write an essay about Good Damage just like Diane tried to do, Mostly a short essay with some philosophy and my beliefs as a person and how the damage I got turned good (you already know). My original name was (Mistakes I don’t regret) but I found good damage to be more interesting and attractive. So if I named my video as this will I get a copyright or any kind of harm etc? Surely I already did a credit and wrote (I used the name from BoJack Horseman show) and talked about the show too.
