Discouraged

I'm in the middle of Week 4 and discouraged. I've been doing so well, eating salads, giving up the dew, drinking tons of water, and eating healthier overall. I don't feel any better. My fatigue level is still high and I don't have more energy. My pants are tighter than before. I'm fighting very hard not to give up. I just wish I could see or feel something that would give me some encouragement.
