Guess what, I'm actually an INFJ. Several years ago, I tested INFP, and for the longest time, I was still INFP... until last year. Skepticism abounds. Then, I started to learn more about cognitive functions. Once I got over the initial confusion, I am very certain now that I am a true INFJ, with a very developed Fi (introverted feeling, INFP's dominant function). Reading about the INFJ personality type opens my eyes to why I am the way I am. It's so liberating.
The above text practically sums up how I feel about loneliness. As I mature, I understand that loneliness is not about the lack of friends or relationships; it's all about the lack of true connection. All my life, I yearn for someone to understand me on a deeper level, someone who truly cares. Because I absolutely do the same thing for them. When I ask "Are you alright?", I mean it. Relationship, to me, is no trivial matter... I don't play around with emotions. My mind, however, is ultra-complicated. To explain an idea or vision to a friend requires some skilled verbal capability, something I'm still not good at. Sometimes though, the ideas that I have exceed my ability to express for comprehension, hence my quietness. I used to think I am antisocial. Now, I know I'm just highly sensitive. A chaotic world filled with so many unspoken nuances overwhelms my mind on a daily basis. That's why, I walk slowly, think carefully and choose intently. If I don't do that, I risk depleting the little energy I have for my own self in order to help others. Such is a life of an INFJ *sighs*...
