How do I make my sim sad?

Is there a cheat I can use or something? My sim is going through a divorce and it feels kinda weird and unrealistic that they just…get over it within 2 days. I get why it’s such a short time but i want drama and depression in my gameplay. is there a way I can keep them sad? I tried sims.add_buff SadHigh but it didn’t work.

EDIT: mod suggestions are allowed too
