I just dont understand...

I just don't understand..why working out suddenly became..so hard! You know the first couple of workouts I was so excited..happy and feeling good..the last couple..I've been barely able to make it through..and the thought of going back makes me want to cry! I just don't understand when and where that transition took place and why I can't get my pizazz for working out back! I know it's good for me..and I usually feel better even if its just for a little while..but geez..I sure dread going! IF Briana had not been with me last night..i probably would not have been able to keep going! UGH! On a positive note..i went back to the doctor yesterday for my (6 months monitored by a physician) weight check and I had lost 3 more lbs. So that's a total of 6 lbs in 2 months..I guess that's better than nothing..I can remember back in the day when I could lose 6 lbs in a day!! Good times!
