worry about my looks

The older I get the more I get worry about myself. I mean like every morning when I look on the mirror I do not like what I see there are new gray hairs on my hair. I do not like my gray hairs that start showing up on my head I hate it. I put some color on my hair but now I have to keep it dyed to maintain the color. When I was young I was not like this but as I get older I worry about my looks and my body I am still overweight but I do not want to take diet pills since I am worried about the side effects of diet pills. I have no plans to take any of them in the future. I know some people thinks that I am getting smaller now but I feel I have lost no weight at all.
