"This is going to be hard, maybe the hardest thing you have ever done…"

A little blurp from my text conversation with my brother last night.  Weigh in didn't go so great.  I keep losing and gaining the same five pounds.  I'm back up to nearly my starting weight.  I'm really frustrated.  I'm doing everything that I've been told and quite frankly I feel like I'm working my ass off. I know I didn't gain this weight over night and I'm not going to lose it overnight, but this back and forth is very discouraging.  I know in the end it is worth the struggle, however I am losing my patience.
