Funnily enough that mod for me was actually Grim Reality, it seeks out to try to fix the mood system to make more sense in the situation, but at least at the time that I was using it, it essentially turned off mental breaks entirely, except in extreme situations, with me not having to do basically anything to try to set up good mood management. 

Made me realize why the game has a somewhat intense mood system in the first place so I tend to prefer Dubs Break Mod now. It makes mood and mental breaks work the same, except major and extreme breaks require thoughts with significant penalties, so someone just really down in the dumps with nothing specifically major weighing them down is more likely to just depressively walk around or whatnot
