What should I do now a year on after a Massive betrayal?

i am 13 and in 5th grade my 3 best friends gave me a hate note and made me the target of the year. each year our class (never me) picked out a boy and/or boy and isolate them and make it so they feel miserable and have no friends. my best friend staid by me and the next year she became the target. we only had each other....... then i told her i was leaving and she hated me for it. we haveint talked yet i am now at a new school (no regrest best school ever) the truth is you will never forget,, but make new friends and fall in love focus your attention on your new friends and your love! i feel for you i do i know im only 13 but i get it. i will pray for you! good luck xoxo gilly hicks girl
