I'd suggest taking out all your mods CC, deleting the localthumbcache.package file from your TheSims 4 folder, then start up your game and see if this sim is still focused. If he is travel through a loading screen and then do something that should put him into a different mood, like cloud gazing or a brisk shower to make him energized at a gym lot etc. Remember: do not save your game with the cc removed as it will be saved in this state... with all your cc missing so when you have finished testing, quit without saving.
