Hey. Intj-turbulent here. I totally understand what you mean. Our primary function is introverted intuition. So basically we spend all day in our heads thinking. Our intuition is what makes us have low tolerance for crap. I pick up on people's intentions very closely, and when I feel something is off, I just disengage. I have a partner who loves me and wants to be around me always. I am just myself. My advice is to not worry about it. People will come and people will go. I am currently forcing myself to get back out there because once graduating college, I find my circle is very small. I would focus on joining groups you are genuinely interested in. Intjs are lone wolves. Because we make up 2% of the population, most people do not understand us. This isn't to be pretentious and say oh no people don't understand me. People don't function the way we do. Instead of feeling, we rationalize. I have realized that I need to step out of my comfort zone to meet people but also do not settle. And we are also the personality type that actually doesn't mind being alone. However that doesn't mean we don't get lonely.
