Help!!!Me friend problem!!!!!?

My friend who moved to Virgina this summer is basically going through depression because she has no friends there.She sits around her house all day thinking about her dumb diet.Ya she is on a freaking diet.She gets mad at her self when she eats yogurt.Or drinks lemonade.She tells me she always feels lightheaded all the time beacuse she is also doing a 5/4 excercise program.I keep trying to tell her she is only 11 and she needs to start getting happy or I will fly there and pounce on you.It is making me so sad.She used to be fun loving and just had fun.Her aunts she had to move with are treating her like crap. They are even going through her diary to read all her secrets.And theyr are deep stuff in there. So I though I was going to write her a poem. LIke this: We have been friends scince 1st grade and we will be friends tell we die.You are a true friend and I loved you personality and all.I just want you to know you will get through this.Your life will get better. Please, you will become the fun loving girl I once knew.So everyday when you feel sad or panicky because you ate a cup of yogurt think of this:It makes me happy when you have good healthy food.It makes me happy when for the life of you you don"t care if you are eating cake or your shirt is to tight.So remember the way you were was the reason we are friends and always will be.
