I loop whenever I do not find a satisfactory answer, and it is even worse because when I was developing I was encouraged to develop Fe, not really Fi.
So when people ask me, "What do you need? What do you want? What do you feel inside?" I am completely off-guard, stumble, um and uh and ah, and have to say, "Hmm, don't know." And that pisses people off because OF COURSE YOU KNOW - you don't want to say! You are not a retard! And when you say, "Well, I guess I am a retard because I really haven't the faintest idea," they think you are being sarcastic until you yell and say, "STFU I DO NOT KNOW!"
And so you go in little brain flips because you are trying to find answers, then analyze the answers, and none of the answers fit, so you brainstorm for answers, and none of the answers fit, so you brainstorm again (this is what people call 'brooding'.)
Then you just get pissed because you wanna be over and done with it, but you cannot because you don't let yourself settle, so you just say, "-UCK IT! I am going with this, right or wrong, because I am sick of this cat crap cream." After that you seriously regret it because somehow you knew it was wrong, but damn it, you're sick of sitting in cat crap cream, and you just think, "Okay what the eff ever." And you're all grumpy and shit, but you cannot fix it, so you start doing random crap to get your mind off the fact that you're really not happy anyway, and well who gives a rat's fat behind because you didn't really know what you wanted anyway, right?
After you sit down and realize my god what the hell is my life all about anyway because I don't even know what my life means and what I want and is it even about what I want and does that even help anyway nah not really but damn it but yes and no together and well, hmm, maybe this but perhaps that.
Finally Te comes down and says STFUUUUUUUUUUUUU!!!!! You listen to me or you die. RIGHT NOW. NOW damn it. NOOOOOOOOOOOOOOWWWWW and Ne says Rhymes with cow and Te says I really don't give a rat's ass, sit down and listen to me and do my shit.
And that's pretty much what looping is.
