"Jealousy is that pain which a man feels from the apprehension that he is not equally beloved by the person whom he entirely loves." - Joseph Addison -

I don't really know why JEALOUSY exists here on earth. Whenever I get jealous to someone or something I feel very sad and I dunno what to do next. I don't want jealousy to become one of my weaknesses. But how can I escape from this kind of feeling? They said you have to be strong and have TRUST to someone you love so that JEALOUSY will not come and ruin your relationship. Is this statement means that whenever you get jealous to someone or something you don't also have TRUST to those someone and somethings?

Oh well, I dunno what to do. Maybe I just really have to be brave and strong when I will be encountering jealousy. >.<
