Every guy thinks that every girls' dream is to find the perfect guy. Please, every girls' dream is to eat without getting fat. But a perfect guy instead wouldn't that bad if he'd accept the fact that I could get fat.
Just keep going! No diet that claims you will lose that much weight/size in such a short amount of time is worth your time. It takes hard work and patience, and there will be "mistakes" but we learn from them and keep going. It WILL BE worth it.
