How often do you sit as a disabled person or able-bodied person, wondering what other are saying and thinking. Did I answer their question correctly! Did I say the right thing at the right time? Will they accept me for who I am? All of these insecurities come from not feeling self-assured or confident in your own being. A lot of our time is spent worrying about what others will say and do.
It is up to us to change our thoughts. It is up to us to elevate our reactions to people, places, and things. It is up to us to change our attitudes about ourselves.
The only way to rise above this is to snatch it by the hands, accept it, and better yourself from what you just heard and learned.
