138.5 lbs. body and mind at war

I'm seriously not liking this scale!! Although I am gaining muscle it really pains me to see the number keep going up, ugh! I may want to stop doing so many pump classes with weights and start some more cardio instead. I can either take a spin class this morning which I for some reason have a small fear of, or I can clumsily attempt to for the third time my step aerobics today.... I think I may have to face my crazy fear and spin today... I think its fear of having a soar rear end after an hour of pedaling, and not from fear of the exercise, but from the little uncomfortable seat... not sure! Anyway, besides the crazy scale messing with my head, I feel wonderful! I am trying to eat lots of protein, staying away from the bread and I've cut way back on my beer, so I'm just not sure about the rising weight, if I keep on I will be back at my starting weight of 161.5 in no time! LOL! I will admit to eating a couple of french fries, but the amount that I had surly would not have given me this kind of gain, its frustrating! I really like being under the 135 lb. mark, and this extra 3.5 pounds are really freaking me out big time! I may need to ask a trainer if this is normal today at the gym, its really the only explanation I have, seriously, I cannot live my everyday life on the 500 calorie vlcd to keep the weight where I want it, body and mind at war today........
