Ugh, ugh family moodlet

It's not. It's because your Sim had a bad relationship with her parents as a child, and now she doesn't like to see those family members whom she had a bad relationship with. It doesn't have anything to do with any of the Childhood phases, it's to do with the relationships you have listed in your Sim's panel with family members after she ages up to YA. I made a thread about this a while ago: http://forums.thesims.com/en_US/discussion/923734/ugh-family-moodlet#latest

So you can't get rid of it by removing any traits because it isn't caused by traits. I think that the only way to get rid of it is to get rid of the entire relationship... which, I think, you'll need MCCC for.

I am not super sure but I remember when I had a kid, they had a time where they hated being around the family. Maybe it is from something like that?

I think it's part of a kid/teen phase from the Parenthood GP.

She's an adult tho. And it's annoying, because she gets this angry moodlet as well as the green good one that praises being around family, at the same time. It's like, make up your mind.

How do I help a young adult get rid of a rebellious teen phase??
