Sometimes I go through periods where I have a very limited sense of empathy. I’m in one of those episodes now. And I hate myself for it. Whenever someone complains or shows sadness, I get frustrated. I don’t care about them. At all. 
I do still feel empathy for a few people, but it’s still a very small amount. 
My closest friend has been going through a tough time. He recently got diagnosed with social anxiety, which I had myself a few years ago. But whenever he gets stressed in a crowded situation, I just think he’s weak. I don’t want to help him, I can’t bring myself to comfort him. I just feel disgusted.
Please tell me I’m not alone in this. I don’t want to be an asshole.
