Im probably over reacting but idc

iv told my sister many times to please not record or take pictures of me while she's trying to record my 12 month old, we both know the same people but iv always been one to try to keep away from them. iv gained weight while I had my daughter and I'm pregnant with #2 so I totally feel self conscious and I hate the way I look & feel. well today i went over my parents house where she lives with them as well and started recording my DD I told her "oh please don't get me" but i just seen her SC sure enough there i was sitting like a old man on the sofa with my leg open. she didn't get my face but it got to me. there has been times where she's asked me not to take pics or record her because she's the same way and I respected that and never take them or post but im feeling petty enough to do it next time I get the chance to. kind of don't want to I'll probably just tell her I don't want pictures taken of my DD so she doesn't whip out the camera. would do yall think? I know some might not feel like this is a big deal but it should still be respected enough if someone straight up asks you to please don't take pics or record
