Let's try this again. Now with long questionnaires!

Gosh, guys, thank you so much for all of your help. This has been a very strange journey of discovering myself!

Of course! Definitely. I have an INFJ friend who's a huge procrastinator and an ISFJ friend whose room is a mess. And then there's me! IxFJ are Pi-doms first, so they're in info-gathering mode. I think ExxJs are more likely to be the stereotypical J's.
Anyone can correct me, though.

I do love my personal appointment book that I keep in my iPhone; I ALWAYS go on it and check off things to do for the day and make sure all of my tasks are done. I have a horrible memory, and I always feel better when I know I've done all I can do for today.

I see no Fi or Ne, only tons of Fe. I also see some Ni, and I notice that your sociotype is INFp-Fe. That being said, IxFJ seems right, though I lean towards INFJ. Your hatred of mundane things and like of spontaneity point towards Ni.
IxFJ's are messy, they lead with Pi and have inferior Pe, no Je there! Je is responsible for that external order, Te in particular has that heavily, while Fe is more of a social order. IxFP's have inferior Te, which in my experience manifests in this external order that they have to keep. IxxJ's and IxxP's will mistype as each other because of the fact that descriptions don't take into account this.

That makes a lot of sense. :O It is crazy how stereotypical MBTI descriptions can be sometimes, and hardly ever taking into account of cognitive functions, which is so important!
