I'd say I'm healthy, fairly fit and active.
I make a lot of effort to cook healthy meals, drink green tea (blugh), avoid processed food etc. I'm not thin, but not exactly fat either, just...plump? BMI 22.5 but I'm short, so I could stand to lose a stone.
I own my house and have a business, really love my job, have a few friends who are lovely, a great partner and freedom to more or less do as I please - a very lucky life.
Why then am I so unhappy not being thin? It's like I can't let myself be happy, because I should be smaller.
How often do you think about your size/weight? How much does it affect your happiness?
