Without getting too specific, I can only say that yes, there are families who are that overbearing.
I don’t know if it’s so much a sin, as it is extremely crude and presumptuous. There are families where every member’s words and actions are constantly under scrutiny by everyone else in the family. They think it is love, caring, concern, and desire to help each other and “have each other’s back”. Very often it morphs into something else entirely.
If possible, the easy way to avoid this, would be just to go to confession without anyone else knowing, and never mention the subject. I don’t know if this is possible for you.
