This is where I get hung up, too. When I was going through a bad time (worst time, really), I kinda let myself go. Just stopped caring in general. I got up to 147 lbs and as a 5' 6" chick, I looked terrible. I felt terrible. When I got a new job and could not fit into a single pair of my dressy/office pants, the sirens in my head started shrieking.  That was all the impetus I needed to get my shit together. Lost 25 lbs in about 3 months, maybe 4. All those new pants (and my old ones!) were now hideously big. Like a little kid playing dress up. New pants time all over again, but this time, it felt awesome.  That was 2011 and I've never looked back. Screw you, fat me!
