Freaking out...I just ate week old chicken?

My family was eating leftovers today and I chose to eat chicken and rice, thinking my mom had just made it on Tuesday. Little did I know it was made last Wednesday. 3/4 way through eating I realized this and got so scared. It was in a fridge which works well. It was stored in a sealed tupperware container and reheated in the microwave. I am freaking out now because I am so afraid that I will get food poisoning. Can anyone offer any help? Have you had any similar experiences? Do you think I will be okay?
