My coworkers are telling me that i am back at my old self

I gained 20 pounds last winter when I stopped exercising regularly and still eating too much.I then I found myfitnesspal and I have been here for few months and the weight has melted off . However my cowers are telling me that I am back to my old self which is great but I don't feel it or see it.My old jeans are still way too tight which means I still have to lose few more pounds. Here are the pics
