Need to get back on track!

OK the madness has got to stop! We got into a really bad habit during our move of eating crap food, going through the drive thru, eating way too much ice cream after dinner....buying ice cream by the gallon and then when it runs out we replace it pretty much within a day or so...this is not normal behavior for us at all and it has got to stop. I'm pretty bummed because we did so well a few months back when we took part in a weight loss challenge but because of being so stressed out from the move we ate really bad food to deal with our stress, so we've gained a lot of it back. Which is hard to admit. I don't know how much because I don't know where our scale is, (part of that is I haven't actually looked for it...) but I can feel in my clothes that I have gained weight back and I can tell from how I look that I have gained weight back. Just in time for summer, right? Ugh.

I need to start drinking water more, I need to just say "no" in the store so I don't have to say no at home after a tough day with the kids where all I'm thinking about is sitting in front of the TV and having some ice cream to totally veg out. I need to start moving more. But I'm so tired all the time. I'm caught in that vicious cycle thing where I don't have any energy to work out and because I'm not working out I'm not getting any energy...if that makes sense.

The bright side is, we stopped eating fast food and I'm cooking dinners again. I just prepped a bunch of fruit to have on hand quickly and I'm about to prep some lettuce and some bell peppers. So it's a start. But why is it so hard?! Sometimes I feel like it can be the easiest thing in the world for me to say no to eating junk and times like right now I feel like I can't buy any will power.

Any advice?
