my best friend and i have been friends for 10 years and she decided to go to a new school a few months ago she didnt have to but she did, now things arent the same. we never talk and when we are togeather we dont have fun. i will ask her to hang out but she says no and goes out with other friends. she is my best friend and i dont want to loose her! she is the only person i talk to when i need help and i am going through alot and shes not there, i feel like i have no one and she dosent even care. what should i do? i tried talking to her but it dosent help.
