Constantly feeling judged

Has anyone else ever felt constantly judged by their mother in law or significant others mother? My boyfriends mom is so uptight and it really bothers me, because she makes everyone else feel bad all the time. 3 of my boyfriends cousins live with us, and now that school is closed they’re home, she yells at them constantly about how disgusting they are because they don’t get dressed as soon as they get up in the morning. She doesn’t even let them go outside during the day so I’m not sure why she’s so anal about it. But then theres me, who’s almost 20 weeks pregnant, and all I can wear is sweatpants and pajamas because my jeans don’t fit me anymore. I obviously can’t go to the store to get maternity clothes because stores are closed, and I’m not comfortable buying online without being able to try them on first. But that’s besides the point. I can’t help but feel judged by her every minute I’m around her. There’s so much more than just this though. Anyone ever have anything similar happen to them? I can’t get away from her because we can’t leave the house. I am beyond stressed.
