Agreed, having people go crazy simply because they've now got artificial parts...is a staple of the cyberpunk genre, but it's one that probably needs a little bit of thought on how you want to handle it. It's a very very common idea in fiction, but it doesn't necessarily hold up under close examination.
You can play the trope straight to good effect - Global Frequency (the comic book) did:
"Try to imagine. You're a multiple amputee who's been flayed alive. You can't feel your own heartbeat. You can't feel yourself breathe. You can feel metal rubbing against your muscles and organs. And you don't recognize the man in the mirror."
But that implies cybernetics suck and don't produce good quality of life. That may not be the case. Depends on whether you're playing up the horror factor or not.
