I think "Cry me a fuckin' river" was not meant to be a statement of contest, so much as suggesting a perspective. That said, both kb's response and your reaction had me cackling.
It's really grating because I'm already going to the gym 2x-3x a week, doing some exercises at home 5x a week, and, you know, have been strength training for over a year now. Because that's my only option. Saying "cry me a fuckin' river" assumes I'm not already or haven't already been trying to work through this shit. I am working hard at this, and already realize I have to work harder than most people to achieve similar results.
Look kleinbl00 was harsh in diction, but nobody here is actually trying to put you down. Anyone can tell from your post that you're working hard and care about your progress.
