If you had the chance to erase one moment from your life, what would it be and why?

It happens on 2011 - 2014, when I was a still in undergraduate major. things fell apart when my mom start taking loans from loans shark without informing my dad, she ordered me to shut it, as this matter is delinquent in family perspectives, and the practice continues until my mom declared, in 2014, that she no longer able to pay it and informed my dad, we were drowned in over USD 100 K debt, my father almost divorce my mom, and I was put into my aunt's house, I was ashamed, I wish I could erase that moment or even did better.
