Bedroom Dwelling as an Adult

Hey everybody! I know it's been literally forever since I've come on here. To make a long story real short, finals have been kicking my behind!

Anyway, I've been living on my own for about two months, and there's this habit I've started to notice on myself. Ever since I've moved in, I've basically only hung out in my bedroom. Sometimes I'd do stuff with my roommates in the living room, but I don't hang out in the living room as a default. 

Ever since I was living with my parents, I just found more comfort in staying in my room by myself. To be honest, I'm not really sure why that is to this day (though I definitely had my reasons as a teenager, lol). 

I don't know, maybe I'm overthinking it. But, I'd appreciate some thoughts, especially from fellow bedroom dwellers.
