I know what you mean. My family's opinion of me hasn't changed at all throughout the 54 years of my existence.
I hope you don't "cut them off," though. There's still room for redemption.
I hope, one day, you could have a discussion with each family member about how you have improved already, and how you are inspired to improve in the future.
You should also make friends outside your family, so you don't have to be around your family all the time.
