Sometimes jealousy will eat you alive. It ruins you. We all get jealous. We are jealous of we thought our closed friend only to find out you're not part of their life. We are jealous of people's look, why they seemed to be perfect and we're not. We are jealous of intelligent people and wishes we have their brains...ANd a lot more!
The thing is how do we deal with it? How can we fight our emotions?
The first step is acceptance.
