There is. I have trouble with this in relation to people. At a certain point, you have to give up trying to be friends with people who don't want it. You have to give up trying to make people happy who are never going to be. And it isn't your fault.
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.
