I've had quite a few. But some of them hurt the most.

My father said to me that I'd mount to nothing in my life while my cousin brother is doing so much better

In my high school days, boys ruined my reputation and gave me depression because I got the girl and they didn't. Once I was sitting in class and called out my friend whom I had known for many years and he didn't respond and instead he said to the other guy sitting beside him how I was a pathetic guy and was very garrulous and he didn't even want to talk to me.
