Only 4.5 months Out and Falling of the Wagon - Venting.
I say wear those sagging arms proudly! It sounds like you are making progress despite having a set back and having saggy arms is an effect of losing so much weight. He meant well and, unlike you, I had too many people who did sugar coat things for me...that probably kept me heavy for so many years. Maybe you could mention to him that his comment hurt a little, but that you appreciate his honesty. From what I read, we all have our struggles. The surgery didn't take that struggle way, but it's good you recognize it and will get yourself straight again. I've been there too.
I know he meant well and I love him dearly which is why I didn't say anything to him. He'd probably be puzzled if I brought it up to him again because I've never been one to be emotional or sensitive about things like that. We've always had great communication which is why he felt comfortable making that comment, but like I said for whatever reason I was sensitive that day..not sure why. Lol
On a different note, I woke up today not being able to find any clothes that fits because it's all big on me. My husband told me I needed to buy new slacks for work because the ones I've been wearing I'm now swimming in them. That was a great feeling! From a size 22 pants I'm now a slightly loose 14...YAAYY!! :)
