As an INTP or maybe more as myself, I have always been feeling inferior when accompanied by estp. I have accepted myself generally, no problems with my self-image, except when hanging around my ESTP friend. Always so direct, fast, decisive, popular. He have no interest in my skills, or my skills hasnt any value for him, I believe. So to the problem, my flaws shine when Im near this person, so I get into this loop, "Why is this guy friends with me, seems to me Im just a leech, not contributing anything to this at all".
This is whining or self-pity at the highest level, and "Its not you, its me"
But seriously, do you think people in your surroundings feel the same way about you?
Is this a game, are you selling yourself to the other person?
