i (f17) have horrible anxiety. recently it’s been worse and i don’t know why. i cant go a day without having at least one anxiety attack, and i’m always on edge. my best friend (f18) tries so hard to understand what i’m going through, but it’s hard for her too i know. when i’m anxious i shut down and get super short and on edge with her. she constantly asks if i’m upset or mad at her and i feel horrible since she’s always overthinking it. tonight we were hanging out and i ended up saying something really shitty to her because i was so anxious and i just snapped. 
does anyone have advice on how to stop an attack or what to say to my friend to help her? i’m afraid our friendship is on the line and i want to do everything i can to help us both. i cant keep doing this every day, it’s mentally draining
