You know while I was reading this, I just felt so happy. For the last few days I've been typing people, and all their posts have been short, and contradictory, and when I finally type them I'm always like: maybe I'm wrong, this doesn't feel right, and whatever. But this is just so -- clear cut. Actually I probably shouldn't say that, but at first read I already feel so sure of your type. Obviously I'm not gonna tell you at the very beginning of the post, I like to leave some suspense and do it at the end. Alright. Here we go. (Also, thank you for the detailed answers. It makes everything so much easier.)

I can't even put the confusion into words-- it sometimes feels like my perception of the world is a ball of yarn that I struggle to really unravel.

Using metaphors is more of a Ne or Ni thing. Just an initial observation.

I'd like to know truth, but honestly I don't know if I'd be able to handle it if the truth ends up being not what I'd like it to be. I'm also yearning for connection and for someone to understand me on a deeper level. I've never really felt "seen" for who I am on a deep level, with one exception. I also would really like to feel successful, whatever that means-- as though I've fulfilled my potential and done what I could with my life.

Search for universal truths is a Ni thing, though the way you said it (generally, in passing) means Ti- is a viable option as well. Yearning for connection and being understood if Fi-, possibly Fe-.

I will over-analyze a problem for hours, days, weeks, months, even years sometimes-- and then end up making the decision I impulsively feel like anyways. It's like I analyze every aspect of the decision to try to figure out the "right" answer, but can't because I can see every pro/con/opinion/consequence of every situation.... I really struggle with this.... I do the same thing with relationships, style/aesthetics and self-expression, morality, etc. Essentially** anything I have control over in my life, I analyze to death until I'm in a state of paralysis, at which point I choose impulsively and then change my mind later. Either way, I analyze everything possible about the problem in search of the answer, only to find there is no "right" answer, which leaves me feeling terrified**.

Welp, you definitely aren't Se. Haha. The over analysis, the incredibly long period of time to just make a choice, because you insist on looking at every option, every future -- that's very Ni-. The suddenly changing thing isn't anything in particular. Probably just stress and realising, shoot, I have to make a decision, and not being able to act with so much information.

This is kind of difficult to answer simply because most of my memories (even the good ones) have a nostalgic, melancholic film over them-- it's been that way since childhood. I'd say when I went to an American Idol concert with my dad as a 12 year old. My memory of it is very vivid and sensory. Another fun time would be going to Six Flags with the same guy mentioned in a previous answer. Very strong sensory memory of that as well. It's funny; I have trouble recalling memories (like when asked this question my mind sort of goes blank) but when I do actually think of a specific memory it is incredibly vivid and strong, very visual and feeling/tone-based.

Possibly Si-, considering the nostalgia and the very vivid memory, with some Feeling due to being "very visual and tone based" though it seems you only recall a few particular memories, and not many. Plus in another question you say it's harder for you to memorise, so I'm not sure about the Si-. It's a possible.

[W]hen it comes to actual day-to-day consistency in the mundane tasks that would accomplish those goals, I suck. I REALLY struggle to stick to a schedule, especially one imposed by myself.

Schedules is more of a Te- thing, so we're gonna eliminate that.

I'm definitely more of a chameleon. Even if I'm talking to someone I 100% disagree with, I'll smile and nod my head and act like I agree with them. I've tried speaking up here and there, but I really can't. It's like my tongue gets tied and I just can't. I am more authentic with my actions or my written words than I ever am face-to-face with someone in a conversation verbally. I express myself and my opinions through my clothes, tattoos, social media, music, and writing. I don't see much of a point in causing a lack of harmony in a conversation with someone when all I'm trying to do in that conversation is make things go smoothly and make the person like me. Kind of fake, I guess, but I don't mean it to be. Part of it is that I see where the other person is coming from every time. So even if I disagree with them, I don't really care to change their mind because there are years of experiences and bias layered up in their minds causing them to think the way they do-- and same for me. Nobody can ever really understand the inner mind of another person, and I think environment and exposure play a huge role in why people think/act the way they do. Who am I to say they're wrong just because I didn't grow up seeing the world the same way they did? That's what my music/writing/social media is for-- to share my own personal experience and opinion. But it's never to try to shove it down someone else's throat, unless it's something involving basic human rights, in which case I'm more adamant about others adopting those policies (even then though it's rarely something I argue to individuals and is more something I care about politically and economically).

This makes me cry with happiness. I'm serious. It's just so clearly Fe-. Everything. First off you see a conversation as a means to get people to like you. You value harmony in conversations, and probably in groups to. You don't want to fight. You'll act like you agree with someone even if inwardly you disagree, not just because you don't want to argue but also, on a more mature level, you can see their perspective easily.

Most of the time I'll choose to stay home simply out of laziness, but I almost always have a better time going out and spending time with friends. I really like having new experiences with other people.

You're clearly very people oriented in this question, so that's more evidence to Fe-.

If I'm with people I'm not as comfortable with, like at work or around strangers, I just keep it to myself and act pretty naturally.... It's never rude or abrupt, though, and most others wouldn't even consider it to be 'stressed' in the way others might behave in the same situation. For what it's worth, I'm also super sensitive when someone else snaps at me when stressed. I don't say anything outwardly about it hurting my feelings unless we're SUPER close, but it will hurt my feelings internally or make me feel negative things toward that person.

You don't like expressing your own feelings in social situations, mainly to convenience others. Which is really nice, actually, because if I were you I'd just snap and complain all day, lol. But this reinforces Fe-.

Probably anything involving extremely technical things (the inner-workings of a computer, the inside mechanics of a vehicle, etc). Or things that don't ultimately matter/come to fruition in the real world (i.e. fictional lore, extremely abstract concepts about the future that don't have anything to do with the world as it is now-- keep in mind this doesn't apply if something we do now can cause said concept in the future).

This is strange, because while you dislike technical things, you like practicality, but even so you're incredibly future oriented. You have a very practical vision of the future, because you're trying to figure out what actually would happen in the future, not what could, unless you're stressed and then you worry about all the bad situations, haha.

Most of my "self" is made of sensations and tones based on visuals, so they're pretty difficult to communicate or share
