Staying on the ball "WHY"

MyPromise

I seem to get started verywell and continue for a couple of weeks and then my momentium declines and I start struggleing to stay on top of the ball and soon after I fall off all together. I then find it really hard to climb back onand get my feet under me moving. I want to keep losing weight yet it seems that I keep faltering over and over, each time it's a little harder to get back in gear and do the things I know I need to do and also feel good after I have accomplished any one or all of them. I haven't figured out the big"WHY" do I keep repeating this over and over again. "WHY" can't I stay strong for the long haul or even past the same 5 lbs lost over and over again. Everytime I see I have lost 5 lbs I end up putting it back on and for me it really takes falling off in a really big way. I actually begin eating a lot of junk and seem to continue until the weight is back on even though after the first day of faltering I tell myself thats ok just make better choices tomorrow. But, the "BUT" that doesn't happen instead I continue to make bad choices until the scale shows the weight back on. "WHY" do I keep defeating myself over and over again. My health depends on me losing this weight and yet "WHY"?????????
