I miss my old best friend?!?

Listen sweetie everything will be alright, time heals all wounds and the more time that passes the hurt will be less. I am long outta school now and have children, im beggining to feel ancient although i am only 29. when i was in school i had a best friend from 4th grade to 11th grade whom i adored but something changed and well we ended up hating each other. i thought it was the end of the world. but now that i look back i realized i wasted a lot of time that could have been awsome dwelling on how bad it was to loose her as a friend. people change and grow apart its just part of life and growing up, people will come and go in andd out of ur life for the rest of it. some will be close friends and others just acqauintences. if u want my advise cherish the memories u had with her keep them safe somewhere in ur heart but move on she has, u have new best friends now make memeories with them and they are in ur life now and shes not really. u dont want them to go away right? show them how greatfuul u are for them. enjoy ur life and the friends u have close and dont let one person make u cry be better than that. i know it hurts but it will get easier and dont ever let her know u cry over her be happy and laugh with ur friends when ur in front of her show her that ur having a great time without her and it will get better i promise. dont sell urself short and dont waste these years u will be an adult soon and wont see the people you go to school with hardly at all after u graduate. so enjoy everything in life that u have u dont want to miss a thing..
