But that's the whole crux of the thing, MollyBerry, nobody actually cares about you - in the nicest possible way - they only care about themselves.
The point of the thread seems to be that there's a lot of people out there, judging themselves by way, way harsher, and more irrational standards than they judge anyone else.
You don't need to feel bad, because it's not about you (generic) and the way the world sees you; it's about the way the world sees the person writing the post. :)
I am 5' 9.5" and wear anything from a size 8 to 12 depending on the shop. My BMI is 22. I know that in clothes I am slim (not skinny), but I find it so annoying (pathetically so, I imagine, in many people's eyes) that I can still pinch way more than an inch of my upper thighs and tummy. To be honest, short of starving myself, which I'm simply never going to do, I think this is as low as my body happily goes. I would prefer not to have so many grabable bits, but hey ho. I'm 39 and at least when clothed I look slim.
Again, back to my original point, I know these are my hang ups that most other people simply wouldn't notice. As I don't notice other people's hang-ups.
It's weird, the dichotomy between the huge amount of pressure to be slim. ... and the way we've (humans) evolved away from the body shape that nature intended (being slim) due to our sedentary, food-available-at-the-drop-of-a-hat lifestyles.
It's got the point now where wanting to be the shape that nature intended when we were active and ate good, un-processed food (not to excess) - and being prepared to make an effort to be so - is seen almost as 'obsessive', 'vain', 'self-absorbed', etc, etc... It's almost more honourable and less hang-up-y to just eat what you want and let the weight creep on. People who watch what they eat to ensure they don't get overweight are seen as the weird ones, the ones with issues...
