a guy hurt me and now I don't want to get out of bed

yesterday night a guy did something completely unwarranted to intentionally hurt me and then blocked me on every platform and I'm just so upset. I won't get into details because it doesn't matter but ever since it happened I've felt like crap. I'm nauseous, my stomach hurts really badly and I have no appetite. I've been able to eat a little bit but everything seems so unappetizing. I feel so irritable and sluggish and I honestly don't want to move or even interact with my family. I've never had this happen before and it's freaking me out. has this happened to anyone else?? what are the best ways to get over it? I've tried my normal self care routine. everything is just pissing me off and I feel super upset. It's dinner time where I am and I've been trying to figure out what to force myself to eat but literally NOTHING sounds appetizing. my best friend is supposed to come over later but I almost want to cancel because I literally feel like I have the stomach flu (i don't actually lol).
