a best friend is someone that means the world to you. someone that you love with all your heart. someone that you wouldn't change for the world. someone that you do everything with, together. someone who is by your side just as much as you are by theirs. having a best friend is the best feeling in the whole wide world. this just makes it a hell of a lot more painful when you're no longer friends. losing this person is the biggest pain ever experienced. how can someone that brings you so much joy, bring you so much pain too? i will never know, but i still care about you, even if you hate me.
a best friend is someone you care about, that you do everything together, can confide in eachother, and trust is a massive key to this
