I would say "and who are you Jesus Christ Mrs. or Mr Perfect!"
Leave them to fend for themselves for a bit. They'll miss you and you get some peace so you can start again fresh. Hopefully
I would stop talking to them for a while.
Bite my tongue. Respect them as much as possible.
Tell them their mistakes
Keep a strong face. Only I know how hard I have been working and make it my goal to better myself for my own benefit and no one else's. Most parents are just trying to push you to be stronger and better.
Tell them to stop being ********.
im very sorry
