Im Over It

Im over it.So I went on Monday to get blood work.A1c was a 6.2 last time this time a 6.1.Really?My cholesterol was 189 and now has gone back up to 222.What the hell is going on?Last time I had blood work done I was not exercising and I was just watching what I ate and everything goes down.This time I am eating even better and walkign on the treadmill at least 3 days a week sometimes 5 as well as weights and toning so I dont get how the cholesterol went back up.I have changed things for the better even more this time than last.I am at a loss and very frustrated.I dont want to be on another medicine.
The one good thing that has happened is I have had to go to a half blood pressure pill until I see my Dr as my blood pressures are so much lower.My Dr says the low numbers are good.Quite frankly they freak me out.Ive never had a blood pressure of 108/68 or 113/72...Now if I could just figure out whymy cholesterol keeps going up and down that would be really great.
I am at a loss and if anyone knows what may be happening please feel free to chime in because Im just all done with it..
