I quit worrying a lot time ago about how others see me. I know my heart and the things I have done for other people.
I also know how often so called friends were not there when I needed them.
If there is any group of people that one might care about what they think of you it would be your immediate family. Unfortunately even that group will often fall short of your expectations.
Life is a wonderful thing and you need to be your own support group. Help those that you can, be a REAL friend to those in need and don't expect any thing in return. You know you are blessed when someone you help or take care of returns your kindness in the same manner.
