How can I make friendship? And stop envying people who have friends?

Im So Sorry All This Happend!!! Im 13 Too And Have Ha Basd Friends In My Times Too! But You Can Be Friends With The Girl That Gets You. The One Who Understands You The Best. And Not An Acctress Like The Rest Of Them! Someone Who You Can Trust! Its Unfair That Your Letting Them Take Over You Then Dump You When They Find Someone Better. Your Worth So Much More. There Jealous Of How Pretty And Good You Are! My Friends All Are Best Friends One Minute And As Soon As They Break Up They Come Running Too Me. Then Dump Me The Next As Soon As They Make Up! And I Get So Mad. So Now Ive Made This Best Friend Mary! And Shes Better And Understands Me Pretty More Then The Others. But Im Used Too There Routine. I Can See Lillys Doing All This Maybe You Should Show Milly How Mean She Is! And If They Break Up They Will Probaly Break Up For A While. Tell Milly Zoe Needs Her That Its Bad Shes Excluding Herself From The Rest And Too Stop Doing This Or She Will Lose Everyone. Maybe Getting Lilly Too Go Back Too Julie! Good Luck!!! I Wish You All The Best!!! I Hope Everything Works Out. Email Me Anytime At adorableaimy@rocketmail.com Have A Great Holiday!!!
