Pretty upset, today I had what was supposed to be my final weigh-in to move on to getting my surgery and I was 1lb over the goal weight. This is so frustrating when I was under the goal weight by 2 lbs last month. I stuck to the same diet that my RD has me on and increased my exercise to ensure I would hit the goal for my last weigh-in. Right now I am so upset and frustrated, it's like my body continuously sabotages me and I don't know what to do. I am going back on Monday to hopefully have lost that one single pound, but I am scared that it's just going to be worse, in spite of my effort.
