“My coach hates me.”

Highly, highly unlikely. This thought is the product of a mind that can’t differentiate between hate and honest feedback.

Your coach has no stake in liking you or hating you; it does not occur to her to label you in that way because she isn’t trying to be your friend.

Join a sorority if you’re looking for friends, but if you’re looking to be a competitive athlete it’s best to find someone who will poke you where it hurts.
