Is it just me or what...

Well anybody that knows me knows that I eat like total crap. I basically eat junk and if I dont have any junk then I just wont eat until I do. I have a BAD addiction to sweets and all the bad foods you can think of. May I also add I basically do not exercise either. Besides cleaning and taking care of the kids I really do not do any exercise.Luckily I am blessed with awsome metabolism and after three kids I have just a few pounds I wanna lose I woulden't say I am "overweight", yes I could lose a few lbs though. My aerobics class on Saturdays I really never go so I am going Mon Wed and Sat for the next two weeks to make up my missed days since I never wanna go!! What I am getting at is I never have any darn energy i am always so tired and never feel like doing anything. I make myself get through the day and its not easy. I am just so tired of being so out of energy i just never feel the urge to get up and walk to the park and run with my the kids. I do it because I know I need to for the kids, but trust me its hard!! So im pretty sure its my own fault because I eat like crap and dont exersice so my body is treated like poo so it feels like poo!! I am wondering though are other moms feeling like this? I do have alot on my plate 3 kids of my own, I babysit another, and go to school. So is it me or is it just how ya feel with all this going on??? I dont know opinions?? Sooooo I am honestly going to make an effort at changing my eating habits and upping my exercise. I am aware of all the damage I am doing to my body by what I put in my mouth, but I does not seem to stop me. I need to set an example for my kids that eating junk is not good for you, and your health is imortant. We also have a treadmil, boxing bag, numerous weights, yoga ball, and the "bean" trust me we are equipped for working out without a gym, but somehow the treadmill is a clothes hanger and the rest are just dust collectors so hopefully I can make use of our mini gym haha we will see.
