gone off the deep end 

You've gone fucking insane until the point where theres a slim chance of being saved. Your friends usually try and warn you when you have but you're oblivious because you've gone off the deep end.

You: I think I wanna get a tattoo of an infinity sign on my lower back. My girl said it'll look good on me

Me: Dude, you've gone off the deep end.
