10 months and counting

This has been a fantastic ride so far. I started at 276 and have been at 190 for several months. I can breathe much better, and I am a LOT more mobile. I got off the breathing machine. I walk much more, and am overall healthier than I have EVER been. So, what is the problem? I feel guilty to even gripe since my life is infinitely better. That being said, it's this last darned 5 lbs. I've been trying for MONTHS to get my final five off and they will not come. I exercise, eat right, do not deviate from the plan, to no avail. Please, I realize how fortunate I am to have such success. It is low priority from a logical standpoint, but in my mind, I still become frustrated. Maybe it's there to keep me humble.
