You are a wonderful, caring person. It is ok to be shy. I have always been very shy. If there weren't shy people in the world there would no one to listen to those who love to talk.
These days you can wear anything and any color no matter what your hair color is. Anything goes. We all have our own special qualities and we all come in different packages on the outside. When I see your picture I see a lovely woman.
What was said in your past is in the past. All your friends here love you and think you are great.
