"Much of my self-image is dependent on something physical: what others say, what I produce; my self-esteem comes from the outside world. This makes me highly sensitive to external influences. If for example, I produce a work of art or do a good job at work, it makes me feel better about myself. If someone comments to how intelligent or interesting I am, I feel better about myself. However I'm also sensitive to the opposite -- failure in the real world leads me into a maelstrom of self-doubt, self-hatred, depression, and nihilism. If, for example, I had a mediocre score on an IQ test, I may obsess over how stupid I am. However, since my self-image is varied and sensitive, it would take some positive reinforcement from the outside world to bring me back up."
"My self-image is dependent on the external world. I feel this is important since I think mine is more in the extreme, compared to the norm. Since I have had no success at all in romantic relations, I see myself as ugly, undesireable, and inferior."
"Sometimes I will "change" my self-perception to set myself differently from others." Fe and Ni
"As much as I am addicted to self-analysis, I have a bit of a fear of my emotions." Not Fi
"I don't make those comments if I know the person will hate me for it, but I do like knowing I shock them and might stand out in their mind as someone who is different."
"In spite of all of this, I do like to be admired and seen as daring by others."
"At first I thought it was going to be an anonymous prank, but I have the urge to brag about it. I already mentioned what I am going to do to several people. I want them to admire me and respect me and see that I am daring and strong. I want them to realize I am powerful and won't let anything stop me from having fun."
IJ:
"I am very cautious of any new experiences."
"Even though I haven't ever been out drinking before, and don't know what it's like, and see nothing wrong in drinking itself (I have no ethical qualms about it), I would still decline because I am nervous of what could happen there. I doubt I could fit in, and I would probably end up making a fool of myself. Besides, I don't have any strong compulsion to go out and drink so what would I be missing?"
There's definitely some evidence I missed, I just skimmed.
P.S. he's a type 9
