Heya ! God it's been a WHILE since I've posted here LOL ! But I've been thinking on something I haven't gotten a straight answer for :

I have an OC , and a part of their backstory involves pretty much being locked inside their house for 4 years at 17 by their dad at an attempt to keep them away from publicity after their mother killed someone .

To be more specific on their conditions :

- They're not allowed outside unless it's absolutely necessary (example , to see a doctor)

- They have one specific friend who is allowed to come over at any time , and they do message on social media via an anonymous account.

- They do home schooling , to explain education stuff .

They finally move out and go outside more when they're 22 , aka 5 years later .

I know that a (likely permanent) damaged immune system would be one of the negative effects due to lack of vitamin D and exercise , but what else could be a side effect , physically , socially AND mentally ? And how could it be for them when actually going outside for the first time again ? I haven't gotten lots of resources for it ..

Edit : Ok so I learned I'm likely wrong on the immune system , but theres lots of traits I considered that I never considered could've been caused by this trauma ..

Also ! It's worth noting that the character would overall lack motivation to do . Anything for that matter , so exercising is kinda off the table and they lack a lot of basic self-care .
