What is with my toenail?? Tmi

It has been like this for years now, i always cover it with nail polish, but its as if it has grown extra layers on it, its so thick😟 i just want to rip it off with embarrassment. I feel like the girl from scary movie when the ghost pulls the blanket off her and sees her toenails lol any help would be so much appreciated... Is there anything i can do? I would love to get it removed and let a new nail grow...
