They set me as a child in a Steam Family and restricted my account

What do I do? A guy messaged me on Discord saying he would unlock more games for me, he invited me to a Steam Family, and now my account is restricted and I can’t play my games anymore. What do I do? How can I get my access back? Did I lose my games? I’m not a kid, I’m 26.

The error I get says that I’m not in the same household. It seems like the guy who invited me is in another city. I didn’t know that wasn’t allowed.

People are saying on the Steam forum that this block lasts 1 year, but I’m not going to stay blocked for a year when I paid for my games.
