Cousin sent me a gore video without warning.

i’m 15 and i’ve lived this far without seeing extreme gore on the internet (i’ve seen blood n stuff but mostly censored on youtube videos n stuff) and the video she sent me had a picture of a balloon as like the thumbnail thingy so i didn’t expect anything bad and she didnt send any text with the video, i stupidly clicked on it and it was horrible.

It’s been like 15 minutes and i cant stop crying, i threw up and i’m feeling really shaky. I dont even want to go back on whatsapp because im scared i will see that video again. im freaking out and hyperventilating please is there like anything i can do to help forget this.
