@TygerNight, you were given some great options to counte act the sadness moodlet that Family Oriented Sims get by @SheriGR , as well as what I said in my first post. However, I think you are more upset about the fact that this moodlet even exists!
My theory on why it exists is that it makes it more realistic and helps balance out all the positive moodlets that your Sims would get if there were no drawbacks. Most, if not all personalities have drawbacks. Sims with the Athletic trait get upset if they can't exercise, Kleptomaniacs get tense if they haven't' stolen something in a while, but sometimes feel guilty when they do steal something, etc.
But I have another theory with the Family Oriented trait... it isn't just loneliness for a family member because that would be satisfied by any family member being present. My guess is that Sims with this trait want all of the family close by them! 🤨 So it wouldn't matter if one or two children of your Sim was present... they might all have to be present to satisfy this moodlet! ❤️
So, try to see if having all of the household in the same room helps at all... Check to see if the moodlet had arrows pointing downward to indicate that the time on this moodlet is becoming lesser at a much faster rate. Also, I haven't tested this yet, but the moodlet might go away instantly. It's worth a try! And if it doesn't' work, try the fixing your sad moodlet or overriding it with positive moodlets with the suggestions that @SheriGR and I gave you! 😇
