In need of help from any of my friends....

I don't know why, but lately I've been sabotaging myself CONSTANTLY. I've been rollercoasting for months between doing fabulous, working out daily and eating perfectly. Then I just crash off and fall into a hole, but I don't just land there. I dig my hole deeper by eating more and exercising less.....  Why would I do this to myself? I have been overweight my entire life and all I've ever wanted was to be average, normal. I know that I can do it... if I JUST DO IT! I've already lost 80, you would think, being over the hump, that my struggles would be less and less and not as if I never lost anything. I lose 10lbs just to gain 7 of that back (I'm not sure if that's exact, but I do something like that) so really I only lost 3. Granted I still lost, but I could be doing it so much faster than what I am.... *sigh* I really need to do some thinking and dig deep within myself to find the power to STFU and do it....
