All my life I struggled with issues related to introversion, and having my own apartment basically solved all of them overnight. I've never been more social in my life than I was when I lived alone. The reason is simple: I was always able to recharge and never got to the point of being consistently drained.
I've been conflicted ever since with how I want to live the rest of my life, as living alone is in conflict with a lot of other goals that are also very important to me, like marriage.
