I'm an INTJ woman. I find it difficult to be like this sometimes because I don't have a great attention span for what I would consider "mindless chatter" or small talk that many other women seem to love. I also can't turn my mind off.
To the OP, I'm sorry you've been dealing with loneliness. I deal with that and depression too even though I'm constantly surrounded by people (extroverted DH and family members). My struggle is that I want to talk about this with somebody who gets it but most people don't really function on a daily basis in that mode of deep self-reflection. When I find friends that do I really love it
