I'm lacking the ability to empathise 或者 sympathise for others?

I've probably 'hardened' myself and become somewhat 'immune' to the empathising and sympathising I normally feel for others. People usually don't come to me when they need to vent, but if I some across someone who is describing their current situation 或者 feelings, I feel nothing for them. For strangers, it's understandable, but for people I've spoken 或者 people I associate with, I really have no interest in their problems. I don't have any intention to help 或者 feel sorry and I'm irritated 由 it 更多 than anything.

Same thing if I try to explain my own emotions. Like, yeah, I'm feeling down, so what? If I try telling others how I feel I usually find it pointless and drop it. I'm starting to care less and less about myself.

What can I do?
