Sore Body!

Today I feel sore. I can't walk, sit, cross my legs, nothing! Because after a month of not working out, I finally did. Busted some Cardio X and I felt AMAZING! But then I stop once I get to a comfortable weight. Usually fitting into a size 3 or 5. Then I just don't care and start eating like shit again. Why though? I mean seriously, how the fuck do I lose motivation so damn quickly? I know I look good, I feel good, I carry myself better and then SAS, it's over. I just let it all go to waste. I don't even want to say, "I'm gonna workout tomorrow". Cause I don't even know if I will. I know my excuse will be that I'm too cold watch. I will try my hardest to get up and actually workout. I hope  I do. I can only motivate myself.
