15 Again: High School Sweethearts

I woke up crying in my childhood bedroom that I shared with my younger sister and step-sister. I was still confused about the crazy dream I had. In my dream I was dying of cancer at the age of 40! Only to find out later that it wasn't a dream! I had been reborn! Time to use my future knowledge to change my life and those I care about! This is going to be great! The only problem is I'm 15 and live with my abusive step father and my mother is always too busy working 2 jobs to notice. Will I be able to change fate? Can I save my sister? Can I change the future? Let's find out! God gave me a second chance for a reason and I plan to make the most of it! Warning: Contains child abuse, attempted suicide and other possible triggers, but it will have a happy ending, so don’t worry!
