Friend is praised for MY work

I’m gonna sound like such a horrible person but I just need somewhere to rant😭. I spent my own time putting together and editing a video. She decided to post it on her account and did not credit me at all. I’m bitter because people think that she used her humour and creativity to made it and on top of that she’s replying to comments acting like she made it! Sorry this is stupid, but I get a bit irritated when people do this. I would NEVER not credit someone for their work, idk why she thought that was ok. She didn’t even ask for my permission. She could of at least gave me credit in the bio/description. Anyway rant over. Does anyone have any advise for calming down? I need a chill pill.
