Why can’t I cry anymore?

This is a weird question. But of course I cry but never when I’m sad. I only cry during anxiety or by mimicry and it’s not a real crying it’s only two tears dropping from my eyes or just watery eyes.
It’s like my body assimilated the fact that crying doesn’t respond to being sad.
Younger I cried everyday because of some abuse (it was only my fault not their) but since then…I’ve never cried because of sadness. Even when my pets or my grandfather died…it was just sad.
Am I broken? Is there any explanation?
