You're fourteen and an Inhuman. Your 'gift' is that you can see into the future, but only how someone is injured or dying. You just accidentally told Fitz how Simmons was dying and it pissed him off. He brought you to a room where May, Coulson, Simmons, Daisy, Mack and Yo-yo are

Fitz: "Why do we even have her at the station?! She is so annoying! She is crazy like her parents!

Your parents were horrible. They tortured you because of your power, so you lived on the base with the others

Yo-yo: "You don't know how hard it is to be Inhuman! You have no right to say that in front of a child!"
