I feel horrible that I'm moving far away from my abusive family without telling them anything. My mother surprised me today with a piece of art and I feel horrible now.
Is their abusive behavior the only reason you're moving?
No, I'm moving to London because I want to get a degree in classic art.
Getting away from an abusive family is the right thing to do and feeling bad about it isn't something you should entertain. Move on with your life and pursue your dreams in art.
But what if they change?
It's possible that they could change, but your number one priority should be yourself, and getting away from them. You don't need to be loyal to your family if they don't treat you well.
