Am I too old to become a doctor?

I am 24, I will be 25 this coming September. Medicine and ballet have always been my top things. I'm alone in the world now after helping my mother battle lupus, but she died last year. I endured a very abusive household that didn't allow for me to study the way I wish I would've been able to, in hindsight, but my dream of becoming a doctor has never left me. I feel terrible because I graduated HS when I was 15 years old, and I could've been finished with medical school by now. I am married... Am I too old to become a doctor?
