Adon, don't beat yourself up over your current situation. That is non-productive. We're all human. What's done is done. Turning your situation around is doable. You definitely can turn this around. I know seeing everyone's numbers here at 3fc was a great motivator to me.. Lots of people losing lots of weight. If they could do it why couldn't I? And there's no reason why you can't as well.
I've found the best plan for me is a combination calorie counting, high protein, low carb kind of a thing. I eat 3 meals and 2 snacks. This way I don't get too hungry. And in just a matter of 3 weeks I was no longer hungry at all and all of my cravings have stopped. I also find I must plan for my day, even the week. I need to know exactly what's on my menu. I also make very tasty food. Lots of veggies, white meat chicken, salmon and talapia, stir frys and so on and so on. I've also added exercise into the mix. I try to walk everyday, just a little bit at first. I have bad knees, no doubt from all of this weight, so lately I've just been dancing, yup simple and it gets me moving. And you can even do this with your kids! I also do sit-ups and I just generally try to move more then I did the day before.
You have to find something that you can do for long-term, for life. At this point I couldn't possibly see going back to my old life-style. It's that quick. 10 weeks ago for me. This becomes your new way of life.
