I was and still am a bit self conscious about my legs. My arms never really bothered me much though. I ALWAYS wear pants. It drives Kurt crazy - he is always saying I wish you would wear shorts. If it is 100 degrees and we are going to WDW for the day .. I wear pants. It has to hotter than #e!! out for me to wear shorts basically.
I was also VERY self conscious about my nails. I had a friend who always used to make jokes about how much nail polish it must take to paint them and how much larger they look when I paint them any solid color. To this day I have a hard time painting my nails any color other than franch manicure. When I do paint them a color I usually end up scratching it all off before it even dries.
I was self conscious about my coughing too, but that has pretty much passed. There were a lot of things that bothered me as a kid that made me feel "odd", for the most part I do fine now. I will also say - in regards to my legs I feel better about it when I weigh more. They don't look so stickish to me lol.
Have a good one,
Lindsey
