That's pretty much it, yup. MC broke something when he told her to go back to her old personality and now the original Chloe is stuck in there, beating her fists bloody against the walls of her own mind...

The question of if MC can undo what he did (or if he should) is one that's going to be explored in a lot more depth in Act Three.
Original Chloe was not a nice person. She was angry, bigoted and at best an uncaring sister to Alice. So the question is: is it better to be free and miserable or enslaved and happy?
