This might be of interest to you, because I am fairly certain my (former) spiritual beliefs caused me to mistype myself for years.
I used to be new age, spiritual, universalist. Pretty much every modern take on spirituality you could think of was lumped into it. I was very into tarot, astrology, the law of attraction, synchronicities, etc.. The idea that there was a divine grand order to everything around us. The idea that there was a god and spirits all around us that permeated everything and effected all. I was raised around this by my mother. My father disapproved wildly. However, they divorced when I was 3, and my mother had primary custody of me so I was around her 5 days a week and my dad 2. Long story short, my mom "got" me. She knew what would comfort me, what would make me happy, and was very devoted and kind. My father tried hard as well, but due to who he is was poor at connecting with me. Overall he's just a harsh person, but a well intended one. I aligned with my mother and was way more receptive to her and her views of the world. One of them was her spiritual beliefs. I ate them up and believed them as a child, and made it into my own. I "saw" what she saw in the world, we experienced things together, and she evolved over time with it. My father rejected this and tried (unsuccessfully) to get my mom to stop and get me to stop believing. However, he went about it in a way that I would have never accepted or received in a million years. So he in effect reinforced it.
It wasn't until I was around 18 or so that I had the first glimmers of "hunh, wait a sec, does this actually fit?". However, I was naturally very idealistic, and unbeknownst to me, I simply wanted everything I believed to be true, and I tricked myself into making it so by using flawed and warped logic. I never consciously considered it couldn't be true. It wasn't until around 2010 that I began to truly wonder in patches. My mom actually triggered it. She was slowly but surely getting more fanatical with her ideas and starting to toe into crazytown. Seeing that, the one person who I (wrongly) saw as an ideal person have major cracks in their make up, really got me thinking. I remember one day I had to convince her sea salt doesn't contain less sodium and she couldn't wrap her head around it, that I began to see.
Fast forward to early 2013, I was getting massively beat up by life left and right and couldn't catch a break. A partial chunk of it was because of using my beliefs as a crutch. Against my own conscious will, I began to think "...there is no rational basis for my beliefs. The same arguments I have used to debunk religion apply to mine as well... uh oh." I couldn't exactly unthink this, and it started a cascade of events that caused by beliefs to slowly die. It alientated my mother a lot, and that will be an ongoing issue. It was painful, but on the other side I have seen that becoming atheist is one of the best things that has ever happened to me. It has made my thinking SO much clearer. I stopped coloring everything in false logic, stopped wishing things to be true, and actually put mental effort into things I usually woudln't because of a spiritual crutch. Being in school helped all of this come to be because the kind of work I do required very very rigorous thinking. It was a matter of time before that kind of thinking leaked into other aspects of my life. In essence, my brain could no longer hide from itself, idealism broke.
For years and years I thought I was an INFJ. I felt it fit me, and at the time it did. My mother is also an INFJ, and I modeled myself after her a lot. My father, an ESTJ I pushed away. I have a tendancy to do a lot of black-white binary thinking, and since childhood labeled my mom as good and my father as bad. I emulated my mothers traits, and rejected my fathers. I am a mix of both of them, the good and bad of them. In my desire to be like my mother, I pushed myself beyond who I actually was by burying unpleasent things of my makeup. Upon the collapose of my spiritual beleifs, those walls came down too because I saw what I was doing with myself. This was part of the painful part because all of the idealism I created for myself (my mother is extremely idealistic) cracked and I had to face things as they were, including parts of myself. But there were some parts of me that lied dormant for long that I didn't realise they were actually good things. They just needed dusting off and practice. With this happening, I realized I am not INFJ, I just fancied myself one (and for all intents and purposes was like one) because of what I emulated (and ironically I was emulating bad things too to create the image for myself). I am not sure of my type, but I am thinking I am xxTJ. I am kind of certain on the I actually, and I am more certain on the T than I have been.
