Laptop Swing Arm

Do i have a right to be mad? ?

Okay so today i needed some help with my laptop since she’s pretty good with computers (we were at school) so i was like patting her i guess and she turned around and she was like “WHAT!?” and she swung her arm around and like hit my laptop and it jumped which screwed it up. i thought there was no reason to do that all i wanted was some help.Her name is Alyssa. so later that day we were talking and stuff and me and my other friend named Meagan were on our way to class and alyssa was behind us and then she said to me there he is (referring to the guy i like) and she was walking with two other girls that i dont really know well she goes and tells them who i like! so now im mad at her.
What should i do? Just stay mad at her? I really hate her right now and i dont want to talk to her.
Thankss (:
