I can't stop crying i lost my best friend! im so saddd?

Okay so i lost my best friend yesterday, well one of them. I have only a few friends left. I lost my best friend because we used to fight a lot when we where younger. I one time hung out with someone else and she said i ditched her. I said sorry, but she said that she couldn't even think about forgiving me. She said i did a bunch of other things. She said my parents always get involved and that i cry my way out of everything. Which i am sensitive and i have been going through a ruff patch with my family. So that makes me more sensitive. Should i just let her simmer for the weekend or should i just forget about her and just deal that's how things are. We are both 13 year old girls
