Is it normal to take a parent role and feel so hurt and broken as a teenager?

I'm a teenager. My dad has been jail for the last five years. It's tough, but my mom really tries to give a normal life to my two sisters, my brother, and I. I feel like I took upon a parent role when I'm the second youngest, and I'm not stable. My mother and sisters say I'm overdramatic. I'm just so hurt, and I keep breaking down.
