Found a worm in my cod?

Okay I am so grossed out. I bought 2 lbs of cod from a local fish market in my town that is fairly new. He told me every morning he goes into Boston and buys fresh fish. I came home cooked all of it and me and my mother began eating. Everything was great until I was almost done with the whole piece. I saw a brown color through the fish. I picked through and it was a worm rolled up in a ball. I thought it was a vein so I picked at it and it began moving. I am so freaked out how it did not die in the oven and will I get sick??
