Need Closure

I recently finished Young Sheldon and started binge watching TBBT. But I feel a lack of closure from YS. Meemaw’s home and business? Missy going through her rebel stage? Mary’s grief after loosing George. Do I need to watch the Georgie and Mandy show, I gave it a try and it just lacked what I was getting from YS. I realize YS is a prequel but it just feels like there weren’t proper endings to character stories. Disclaimer I’m new to the group so maybe it’s been discussed before but I would love to hear from y’all :)
