Most people I know who have lived most of their life overweight/obese have a pretty strong aversion to cameras. We prefer certain angles and to be photographed from the shoulders up.
Focus on the pretty face.
I've mentioned in passing and a bit more in-depth that I'm a skin picker.
I often don't want to be photographed if my skin shows the damage of my anxiety.
Because of this I have become pretty good with makeup and fantastic with photoshop.
My admission for this post is that I'm also really sensitive about my teeth. My mom had dentures by the age of 36 (I believe). My dad grinds his teeth. As my permanent teeth grew in, my baby canine teeth didn't fall out, and my adult ones grew on top of them, making it look like I had fangs. (I don't know how accurate it is to say it was a genetic thing, but I know of a few people in my family that had this happen as well.) I had braces for about a year and a half to correct this.
If there is one doctor that I make sure I see, it's the dentist. I do everything they ask of me (floss, proxy brush, different brush, fluoride rinse... you name it). I just ask in return that they promise me that I will keep my own teeth for a very long time. They assure me that I don't have my mother's teeth, and I don't have my father's behavior.
However, over the past few years I've been increasingly sensitive about the color of my teeth.
I wouldn't say they're yellow, but they're like the color of tapioca pudding. They're just not as brilliant as I would want them to look. I don't want them to look unnaturally white, but I want them to look like how I live (ie, I'm a non-smoker, I don't drink coffee, I don't drink red wine...but I do drink tea...).
Today I'm going to spend more than a few dollars on myself to get in-office teeth whitening. I have a hard time spending money on myself, especially for things that might be frivolous or aesthetic in nature. It will have an effect on my diet for the next 36 hours (i.e. no food that can pigment my teeth while the enamel re-closes) and most likely until the wedding (i.e. no red wine, limited foods that can stain my teeth).
I feel horrible feeling vain, and spending money -- but if it works on my teeth and I feel a little brighter.... then it will be money well-spent. One less thing to feel self-conscious about.
