HELP I accidentally ate shrimp

I accidentally ate Shrimp “product”/ oil. I was at a Chinese restaurant (not kosher as there are little to no kosher places where I’m living.) and I had ordered chicken fried rice, I asked the employees there if they fried seafood and the chicken separately and they said yes. I felt very bad a little while after I had finished eating and realized I had gotten some sort of seafood/ oil in my food. (I am allergic to seafood so it was clear something had gotten into my food)

What do I do??
