Everything hurts

I'm surprised that my weight has ballooned back up into the 300's. What is even more surprising is how freaking tired I am all the time and how even the smallest amount of exercise wears me out. I used to go for walks every night and I miss that. I was up to 30 min on the elliptical. Now I can pull out 10 with a mighty effort. I'm looking forward to getting some of this off so I can just plain move easier.
