Bill - My dad is from SE Texas, near the Louisiana border, and down there crayfish are called crawfish (which is the fancy term) or more usually crawdaddies or even mudbugs. And they are delicious.
Ah, our old friend obsession. I actually saw a counselor for some of 2011-12 - I ended up talking about a lot of things, but the main precipitating factor that got me into counseling was my obsession with food/calories/weight loss/changed body image/all of it. (I reach GW in the summer of 2011 and had a heck of a time adjusting.) Seeing a counselor helped some, time helped some, but mostly I'm aware that there will always be a level of obsession.
Alizarin - I've had many of the same thoughts you've had. I, too, have calculated others' BMIs, in order to see where I compare! For me, I'm aware that's not mentally healthy behavior and I'm actively working on seeing others' stats and then choosing not to think about then or apply them to myself.
It's cheesy and cliche and all that, but I really do think to myself sometimes, "Comparison is the thief of joy." When I compare myself to others, I only hurt myself.
Of course, this doesn't help when we compare ourselves to the weights that we've been before and want to get back to!
I do wonder when/if I'll ever be happy with my body. As is the same with many of you, I'm at a healthy weight and physically fit in many ways. I mean, I used to weigh more than 200 pounds and get winded walking up one flight of stairs! But I can't get the "five more pounds" whisper to leave my head. And, although I'm very close to being back under my red line, I'm already thinking about how much more I want to go under it.
