My mom called me fat?

I am 5 foot 5 and weigh 130 pounds. She told me that I need to lose weight because I look a little on the fat side. Do you guys think I need to lose weight? She wasn't joking around either, she really meant it. Maybe she actually wants to lose weight herself? She's 5 foot 2 and weighs 150 but she is always pestering me about my weight. It's getting really annoying but I'm starting to believe I need to lose at least 15 pounds. Honest answers please.
