I became a quiet person because of antipsychotics

I dont groan with pain anymore, i don't cry. I don't smile or laugh like before. I'm completely expressionless. Not to mention the loss of my cognition. It's like i'm not human anymore, just a lobotomized doll stuck inside my own body. How is this legal? I was fine before. Do people get from this or is it permanent? The way it feels is that it's a part of me now. No way this has something to do with receptors, it's probably brain damage.
