Will I get sick from frozen raw chicken not properly cooked?!

Today for lunch at my school I got the general tso's chicken. The first couple pieces I had seemed fine, except one was a little mushy. When I got to the fourth piece I took a big bite out of it and it felt and tasted funny so I looked at the remaining piece and it was completely pink and not cooked. I then spit out the piece that I had in my mouth and went back up to the kitchen part. I think what happened was that the chicken was frozen and hadn't been thawed before it was cooked so then it didn't cook. I'm extremely paranoid that I am now going to get sick from this. What's the chance that I will?
