Must regain control

Starting around Thanksgiving (actually probably around halloween) I completely lost control of all healthy eating. The junk is in the house, and I can't say no. It was a mixture of pity party and not caring and then the holidays snuck up on me. Not a real good excuse but oh well.
Today I weighed myself before getting dressed and about died. I'm up 7lbs from my weight at the end of the study (which was up a few from my maintained summer weight) and that weight I was fully clothed. It's just sickening because I worked so hard last year. I don't even want to see what that weight would be if I was all dressed in my winter clothes. I refuse to let it get out of control again so the first thing I did after getting dressed again was come down and throw away ALL of the cookies we had left over.
Last week I went into a major baking spree and we had 4 big containers of cookies left after I gave trays away on Christmas. Everyone in the house (minus Kristopher) is in need of a diet. I'm apparently the only one who cares but seriously, what does it take for them to wake up too?
My dad is diabetic and is eating huge servings of all this junk like he doesn't have a care in the world. My mother is very overweight and is doing the same thing, even though she doesn't feel good after eating the junk. And my husband is heavier and overweight but keeps doing the same. He has also said that sugar is making him feel really icky lately but won't make any chances to that. I did it for them all. The junk food is gone. I refuse to buy anymore and I'm going to get back on track. We have a treadmill that is sitting out in the garage and it's about to make its appearance in the house. If I could just figure out how to get it up the few steps and in the door without killing myself it would already be in here.
I really do not like the treadmill but it's way too cold to go out and walk and keep up any type of regular routine. I'm guessing it will help if I force myself to get on the thing on a regular basis......
I also have started to feel like total crap again. I know it's the way we're eating but it is nearly impossible to find healthy meals that everyone likes. That's going to change though. If I am the only one cooking then they will either eat it, or starve.
Mean scale just ruined my day......
