In an anger rut

I have lost more in the past six months than I thought possible and I am starting to really comprehend how deep the changes have been regarding my health and habits. But, I am pissed at myself because i have stopped exercising! It's been about two months now that my exercise activity has dropped from almost daily to four or five times a week, to two or three times a week and now less than once a week. I am still losing, although my weight loss has slowed to about 2 lbs a week (which is still awesome!!!!). I am only 20 lbs from goal, and I know I will make it. Yet, I am still angry about not exercising and not finding the motivation.

Actually, I seem to be angry about everything. I just get pissed all the time at the littlest things. My family is walking on eggshells around me, worried that they will upset me. What the hell is going on? I have achieved something I am proud of. My body doesn't hurt anymore. I feel like I can tale anything on. YET, there is this seething beneath the surface that just won't quit. I recognize that the anger exists (yeah therapy), now I just have to get to the bottom of it. Could I really be so upset that I can't eat as much or as many things as I used to? Am I really missing food that much? I have to get over it, because I have not come this far to not enjoy this new opportunity!
