Wake-Up Call

Two and a half weeks ago I decided to step on the scale since I was no longer able to pull my jeans up over my hips and was shocked to see that that the 125 pound frame of my youth had exploded to 182 pounds. I about fell off the one inch tall scale, which is lucky for me since at that height, and weight for that matter, I would have busted a hip or sent shock waves throughout my house rivaling those of a magnitude 8.0 earthquake. Talk about a wake-up call. Now, obesity runs in my family, thank you Millmans, and pregnancy and my parents complete disregard for my nutrition when I was younger has evolved into poor eating choices and escalating weight gain comparable to a baby elephant. Geez, I haven't weighed this much since I was in my ninth month of pregnancy, with all three of my children! This is, well, unacceptable. This has to change now!
So I brought up my climbing weight with my ever supportive hubby, who lent me a few words, bless his heart and his loose lips. He said that he had been eyeing my now very rotund backside thinking, to himself of course, that it has become bigger than he had EVER seen it, even more so then swollen, pregnant wife. That was more than a wake-up call, that was a sheer slap in the face. I can't hold it against the poor guy, he was right. So begins my journey to rediscovering myself, and my gluteous-maximus.
I began exercising that day and severely cut my calorie intake as well as those yummy 50 calorie truffles and eggnog I was enjoying, and using to celebrate the festive season. 2 1/2 weeks later, I am only down 5 pounds. I am exercising 1 1/2 to 2 hours a day doing aerobics, kick-boxing and weight training.So why after all this work have I only lost 5 pounds? Granted, I found my biceps and I think my inner thighs are getting less friction than before, but 5 pounds?
I think god personally decided to play a cruel joke on women, making it ten times easier to gain weight than it is to take it off! Now I have learned that you have to nourish your body for successful weight loss, which I have substituted all my meals with healthier versions. So despite my obvious disappointment I continue my vigorous work-out routine and strict diet. Does anyone have any ideas or words of encouragement, since I feel like I have just stripped off all my clothes and bared all? How do I stay the course and stay motivated while boosting my results?
