Showing my true, real self is hard. Bullied, teased, made fun of for who you really were is hard to come from. That's why people put up walls, barriers, masks, to hide behind. They're afraid that people will do it again, just like the people before.
"Don't Take Anything Personally. Nothing others do is because of you. What others say and do is a projection of their own reality, their own dream. When you are immune to the opinions and actions of others, you won't be the victim of needless suffering." ~ Don Miguel Ruiz
