OMG IM FAt???

I went on this overnight retreat with my BFF. Her mom was there, and the lady is insane and thinks that shes the whole worlds personal trainer and so she wants to put me on a diet because she says im fat. im 5'7 and weigh 132 lbs. is this fat? be honest because i want to tell her off. like when i was changing, she was all like "look at how fat your stomach is! Oh my god cover it up its disgusting!!!" she is 5'7 and weighs 122 lbs. and my friend is 5'5 and weighs 111. She wouldnt let me eat like chips or anything all weekend because she says it is bad for me, and she like made my whole weekend miserable. so, am i fatt? oh, and tell me your opinion, not "your bmi is fine, youre in the middle"
