273.8: WTF? +4 lbs in 4 days!

So, I gained 4 lbs this week!  I had been working out regularly, felt better, was less tired, had more engergy to do things and then...I went to my parents for the weekend.  I thought I would still workout, but my dad got sick and had to go to the doctor.  He's still there.  I didn't eat a LOT when I was there, of course, there is never a LOT to eat there.  I guess it's just stress, but really, who gains 4 lbs in one week.  Isn't that just a little rediculous?  I just don't get it.  I wasn't lazy, when I did over eat, it wasn't any more than usual. 

I'm just frustrated.  The week before I lost 3 lbs.  I was so happy.  Working out had paid off.  Then, this week, I gain it all back plus some!  I need to count calories again, I know.  If I only had time.  Why is life so frustrating??? 

I'm keeping this one short.  I will get back to the gym and I will work out, but I feel like the girl on Biggest Loser who purposfully gains weight.  I didn't, but who's going to believe that I didn't eat that much?  I didn't even have a single donut...which is a staple at my parents house.  Most times we eat two meals of donuts....
