I'm definitely an introvert. It usually takes me a lot of time to "warm up" to people, really trust them and really be myself around them. And even then I'm not much of a talker most of the time.
I have only a handful of friends and am usually shy and awkward when meeting new people.

And, like others have stated, I also need a lot of time to myself. Like, I've tried imagining living with a SO (if I had one)... and I just can't imagine being with someone else most of the time, even if I loved them. I just need my "computer/TV/reading" time to myself every day

Also, my test result is INFJ.
