I think it is just general human condition to think "who am I really" so it is not just you, everyone does it to some extent - but this is overamplified in INFJs. We are preoccupied with finding meaning in everything around us, especially human existence, and especially our own person more so than people of other personality preferences. In past when I had some guys confess to me that they like me, one of my first thoughts was "is it really me that they like or just this version of me that I have been presenting". Then it leads to feeling of being a fake, sort of like an actor acting a particular play out on a stage. Come another play and you'll be acting out another role yet again. So then how can people really like you if they don't know you? If you don't know yourself?
Way I get around this is first of all by focusing on the moment and sensory stuff. Second thing - instead of overanalyzing the situation, focusing on the future possibilities. First method drowns out the workings of intuition. Sensory and intuitive functions cannot work at the same time in your head. Second method simply extraverts the overactive introverted intuition. So instead of overanalyzing who I am, my imagination of what can be done in future flourishes. I basically assume ENFP/ENTP-like personality qualities - if you have ever interacted with either type within a relationship, at the beginning they imagine all kinds of rosy future possibilities. Either way dampens my Ni doing crazy stuff to my sense of myself.
Being around other people and taking trips certainly helps to reconnect one better to oneself and world around, as least for me.
