What should you do when you are fed up of being invisible?

First of all you could never disappoint your gran she knew you the way she did and loves you for who you are. She will she you as the great person you are and always will no matter what others think. I have the same exact problem in my life and the feeling of being second best to the world hurts like hell. You need to realize how important you are and focus on those people who do appreciate you. I am finding those friends in my life and things are really looking up. But it all starts with viewing yourself as the important person and realizing that there isn't anything wrong with you there is something wrong with the people who don't notice your light. Bring out that person who gran saw the greatness in and make people see your beauty. It may take a little while but those people who notice are the people that matter. Find your light.
