I cringe at someone confessing their feelings to me
Why do you cringe at that?
I don't like to hear about other people's feelings. That's totally not cool for me.
You shouldn't hurt shut out a friend just because they are sharing their feelings. You should learn some empathy.
Why do I have to be forced to endure someone droning on about their feelings?
You should concern yourself with how others feel because that's what friends do. You're not going to have many friends if you don't show sincere interest in how they're feeling.
