to me the song is about someone he once had a relationship. She probably tore him apart and left him broken, and he hates her for that.. shes is the pig

hey pig yeah you hey pig piggy pig pig pig all of my fears came true black and blue and broken bones you left me here all alone my little piggy needed something new

She left him for something new, a new relationship. Now he doesn't care anymore. He doesn't feel anymore.

hey pig nothing's turning out the way I planned hey pig there's a lot of things I hoped you could help me understand what am I supposed to do? I lost my shit because of you

This verse shows that he's still lost without her although he says nothing can stop me now. And I feel the repeat of the line (nothing can stop me now), he keeps saying to himself to convince himself that everything will be ok.
