harry potter fanfic time travel

In my previous life, I had been suffering from a terminal illness when I won the lottery.  To my shock, Mommy advised me to forgo treatment and leave the winnings to my younger brother, David, to use for his marriage.  I refused to become an accessory to his future, so, behind my parents’ backs, I donated every bit of it to an orphanage.  When they found out, they were furious. They called me a heartless, ungrateful wretch.  After severing ties with me, they abandoned me at the hospital. On David's birthday, they gathered as a family and celebrated him while I was left to die in the hospital, utterly alone. When I opened my eyes again, I found myself back on the day I had won the lottery.  Recalling the pain and betrayal of my past life, I resolved to leave my parents that very day.  But to my surprise, when I returned home, they had completely changed.  They doted on me and showered me with affection.
