Got my first stone help😭

I (22yr female)have been dealing with what felt like a pulled muscle by the left side of my ribs for maybe 3 weeks now. But this pass weekend I developed loss of appetite (I would still eat) and nausea so I decided to go to the ER. Turns out I got a 2mm kidney stone and some other issues unfortunately but yall what do I do I’m very scared 😭 I also hate vomiting and knowing that it’s a symptom has been eating me alive. I just want this to be over :(
