Best Friends !? Adive Please ! 10 Points To Best Answer .?

ohkay well i have my best friend and well you can say we have a really funny background . in 6th grade we went to the same school and we never talked ; although we kenw each other since we were in the same class we didnt talk . i left in the end of the year . while in early 8th grade i was on myspace and saw she had a myspace . randomly adding her cause i remembered i knew her a bit i sent it . we eventually started talking only a bit . shes the kind of people who have alot of friendss and really doesnt care about anyone but herself . like its ahrd for her to be close to someone and care about them . its also really hard for her to show her feelings . but weve both been through alot individually . come to say that in less than 1 year we ended up going to the same high school . we became really close ; closer than ever ! best friendss and everything , and were still close . i know she reallyc ares about me and shes often told me that she happy . i taught her something valuable . How to care about someone other than herself . to know someone is by her side ; she said that even though shes had many friends she has never truly cared about anyone like me . and i believe her . because i can see it . i on the other hand have been through betrayel from other friendss and well you can say i depend on her ALOT . just like her ! this is something new to her because shes never been so close to anyone as close as we are . but i know she truley cares about me and loves me ( as friends ) . but i guess that since ive been let down so much and ive been treated bad by other friends im afraid shell do the same . howd of i get rid of the negative feeling ? ive talked o her about it . shes promised me that shell always be by my side . that she will never let me down . i truley believe her . but even yet i get insecure sometimes , what should i do ? what should i think ? help me please .
