While I need a fair amount of down time and alone time, I do need to be social for my mental health I have found. Isolating myself makes me more depressed sometimes and also socializing with friends can be a bit grounding for me if I am just spending too much time ruminating and getting anxious on my own. Once I have stopped being social for awhile I find it hard to get started with that again, though. My social anxiety picks up a bit and I have to work through that.
