First, congratulations on all the things that are turning around in your life! I am jealous of your old house!
The good news is that you are *only* 152 lbs! I say that as someone who came here at that weight

. I'm not saying that to diminish what you are feeling, I am saying good for you for getting serious before it was a lot more weight to contend with.
Here are a few random ideas:
I know this feeling well about just wanting to EAT, and not usually salad (probably most of us here can relate). Do you have an eating plan? You can always switch later, but it seems like having a plan is the only way to get started. XXX calories, or XXX points, or South Beach/Atkins/whatever. At least that gives you a structure to get started.
PLAN out your day! That is critical for many people, especially when you are beginning. Oh yeah, and then stick to the plan. (that appears to be the hard part for me).
One trick for the eating, not that I am so good at it, but bargain with yourself that the only way you can eat some treat is AFTER you eat whatever healthy thing you had planned. Force it down. Most of the time, after you get through the salad/whatever, you don't want the thing you were craving before. Of course, if you still do, you have to have some serving size in place, like 1 square of dark chocolate. And at least you have something nutritious in you already.
If you choose a plan that allows fruit, I am finding that fruit can often substitute for a sugar craving (duh, it's still sugar!) but is so much more healthy. I've been eating a lot of apples or pears with lowfat cheese or natural peanut butter (measured out).
I have been making yogurt smoothies in the morning - with yogurt, protein powder, a little bit of sweetener and blueberries or cocoa powder. I find it a good way to quickly slip something healthy in when I am not feeling up to cooking and get the day off to a good start.
Personally, I would say cut out the fast food altogether as a first step. Not good for you, not good for your kids (setting up bad habits for the future, I say as someone who ate fast food a lot as a child). Have some backups in place for those times you are working late and don't have time or motivation to cook. Frozen Lean Cuisine-type meals- not that I'm really advocating them - are better than fast food (actually I found a salmon with veggie and whole wheat orzo- Healthy Choice maybe? - that I would eat when pressed for time. Amy's has a lot of good stuff...) A pizza on pita bread takes about 5 minutes to slap together.
I found joining the exercise challenges here at 3fc have kicked my butt into exercising more. You could add some DVDs for strength training to supplement your treadmill work - some of them are only 20 minutes long. Also, you could do Couch to 5K or HIIT intervals on your treadmill to mix things up. These are both discussed a lot in the Exercise section here.
Consider looking into the
Beck Diet Solution by Judith Beck. It's a psychological approach to losing weight, focusing on good habits rather than any specific diet. A lot of us here have found it really useful in turning things around. I recommend the pink book - it goes through a 6-week plan, but the green one has most of the same stuff, it just includes an actual eating plan.
It's about 2 months till your vacation. I'd say realistically you probably won't lose more than 10 lbs, if that, BUT you will have great habits in place by then and hopefully you will have dodged the holiday gains. You'll be ahead of all the New Years resolution-ers and will be off to a great 2011. Come post in the featherweights chat and let us know how you are doing!
