Jesus, hopefully I'm not offending you here but your dad is terrible at teaching lessons. 11PM-7:30AM is more reasonable (only on school nights) but holy stuff this sucks for you. I honestly hope I could do something to help. If your dad puts that much stress on your mother that is not good whatsoever.
What did your sister do to get here stuff taken away for 3 years btw? Or is it sensitive/private material?
