This feeling comes from my own experiences that I am at my happiest, best self when I'm alone. And I don't understand how starkly this contrasts from what I hear from others and from studies such as this one.
This isn't a "I'm an introvert" or "people suck" anecdote. This is something that I repeatedly try to objectively access and measure, and almost every time my body responds better to being alone. The less people I have in my life, the better I feel. The more time I spend by myself, the better I feel. The less I speak to anyone, the better I feel.
It might be a bit ironic to ask this, but am I alone in this feeling?
