  No one fails to feel. That's true, but not the problem. No one fails to feel, but many fail to show their feelings, or tell anyone about their problems. They should get it off their chests, though. No one can go through life always being sad, and not letting anyone help them.
Friends don't want to know your problems because they're nosy. Friends want to know your problems because they want to help you. They want to make you happy again, and that's not going to happen if you're always sad, but won't tell anyone what's wrong. There's nothing wrong with confessing things. There's nothing wrong with feeling.
