Life gets in the way (SS)

My life has suddenly gotten in the way of diet and exercise. I can see where it all starts taking an out-of-control tumble back in to sedate living and bad food choices!
I'm back in management until sometime in May! This means back to work Monday-Friday from whatever time I go in to whatever time I leave. This has been going on for a week now.
This past week I have exercised ZERO times!
This past week I have had some form of chocolate for lunch!
This past week I had cold pizza for breakfast!
This past week I have drank beer-a lot. All in one night.

I left work yesterday (Friday) and drove straight to the Hardings liquer section.

I have a daughter getting mattied the end of May. She is calm. I have begun panicking.
We are on the phone re-arranging plans and making final ones.
I have a daughter needing help with a 20 page research paper. We have been doing a lot of it over the phone.
My husband has been working his full time job and then three nights a week he is bartending. I have been spending my evenings at home alone talking to the oldest daughter and helping do research with the youngest, but not eating dinner or just eating nuts or smoothies because I don't feel like cooking for one.

I know why I got fat in the first place. I didn't pay attention.
I haven't gained any weight...yet...but I feel unhealthy.

Got to figure out how to calm life and get back to my routine!
