She asked me to promote her “it works”

OMG. So one of my old friends from grade school just messaged me asking me to start promoting her on my page. (I have more friends and more of a following) well I immediately message back and just lay it down. I’m pregnant and obviously I am getting bigger I’m not about to start posting things about weight loss?!?! How rude!!! I told her I’m pregnant, not fat and I’m not comfortable promoting that on my page and making people think I’m just fat. Maybe I’m over reacting but that hurt my feelings!!!!
