I'm not trying to make light of your situation. I'm sure if it were me, I'd feel the same. But , sometimes we gotta put our big girl pants on, and deal with things we don't like. You work because you need a paycheck. If you didn't you wouldn't be going back. That being said you have far too much on your plate (no pun intended) to focus on besides office gossip and petty drama. just go in there, focus on your post op diet, and who cares what they think?? you dont need their approval, honey. It seems like a big deal now, but it will pass, and no one will care about it once you return back to work. and if it really bothers you that much to discuss it-- just simply say that-- I'd really rather not discuss it, but thank you for the well wishes, or something like that. no one will press you for more information. dont stress yourself over this.
