You need to have more friends, so you don't feel as if your best friend should only be with you and not with others. The more people you both know, the better for both of you. You are too tightly attached to her and that is why you are so jealous of her relationships with others.
Clinging to her too tightly will only make her think of you as a difficult person to remain friends with at all, especially if you become sullen and sulky whenever things don't go your way.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
