Especially since shes the same age as me. But I've been called fat phobic before and I've had people refuse to work with me before because of it but lately its been an issue and I dont want to offend her but I want to talk about my obsession with weight and fear of gaining it but I'm worried she's going to think I'm secretly judging her or something.

Does anyone have any suggestions on how to talk about this without a bunch of unintenional offensive bullcrap coming out of my mouth? I dont have the best social skills.
