Hey, if I can survive 5 days from **** being surrounded by my in-laws, stuck in a hotel room for three days out of five because my husband and I had a fight about their cruelness towards my kids, and hence, I did not go to his brother's wedding, anyone can do it!
Oh, and for all my pain, humiliation, and hurt that my *bleeping* husband put me through, not talking to me or seeing if I needed anything to eat or drink or if I was alive or dead those three days, I gained back two pounds.
I didn't even eat much, I stayed under 1600 calories a day, some days less than that, but the food sucked. I had to go to the Jack in the Box one night and get 3 breakfast items to eat for that day, the next day, I had to go to the store across the street at 5:30 am when it wasn't busy, or I'd never get across that highway. That store had premade sandwiches, so I bought one tunafish, one turkey and cheese, and one ham and cheese sandwich, two packages of Rice Krispie Treats which were 310 calories each (I ate those for breakfast the last two days) and two small packages of Combos. There were no stores that had any fruit or veggies around me.

I was stuck in a hotel where there weren't any decent food places, so I had to make due with what they had. My exercise was basically walking to the two food places, crying, and swimming when all of my family was out of the hotel. Yet, I still gained two pounds and can't seem to lose it since I got back on Monday.
I'm not giving up, though. I refuse to let what happened last week depress me into eating. It just proved to me that I need to care more about myself and to take good care of myself, because nobody else will do it for me!
Oh, and I can relate as far as taking care of Mom. I lost mine 14 years ago, but took care of her for most of my life, as she was chronically ill for almost all of my life. My Dad died before her, and my siblings were of no help, so it was just me and Mom for a few years, then hubby, Mom, myself and my oldest daughter until she passed away.
