Ashlah: Take whatever positive strokes you can give yourself. It can be a challenge to treat ourselves well, sometimes.
Before we had BMI, we had height/weight charts. If you are X feet/inches tall, you should weigh Y pounds. (Substitute meters, cm, kilos, and/or stone as preferred.) These ideals were equally bullshit, and possibly more. A small-frame person who's 5'10" could well weigh the same as a large-frame 5'4", and both could be healthy and fit.
Really, the only measures we should use are:
1. How's your cardiovascular health? How long can you jog before you're breathing too hard? How many flights of stairs can you climb, or how long can you push yourself uphill in your wheelchair before you're ready to give up?
2. How well are your joints bearing up? Are your knees and/or hips wearing out before their time when there's no underlying condition (e.g. arthritis)? Are your feet getting so bad you might be unable to walk one day (except for non-weight-related flat feet problems)?
3. How happy are you with your weight? Does your size prevent you from doing things you wish you could, such as going on roller coaster rides? Can you realistically change your size if you are unhappy with it? (That is, is your basic frame larger than the size you wish you were? If it is, it'll be better to change your expectations than your weight.)
That's pretty much it. If you're healthy, fit, and happy, FUCK WHAT ANYONE ELSE THINKS./'scuse the outburst.
