Well yeah there's got to be a bit of that.
At the height of my weight (err...), I was indeed unhappy. Suddenly it didn't look like me in the mirror or in photos any more. But up until then I'd managed to get over the weight gain and be contented anyway, although always hoping against hopes that I'd stop growing outwards...
At the last visit to the doctor, as I am now under the obesity BMI and in the 'overweight' zone, he asked me what size I'd like to be, where I'd like to stop. I won't just balance out by myself, I'll just have to moderate medicine and food at the level I am happy with.
You know, I couldn't answer him easily, as I'm not /un/happy now. Almost feels like I'm cheating if I keep going, like wanting myself to be slim is a shallow thing to want. Very confusing.
