This actually really great that you're getting these charts super straightened out in your mind. It says себой, should be собой. Perhaps note, that instrumental pronouns ( just like some nouns), can take a ю ending instead of й: с тобою. It has something to do with ukrainian I think. Not sure if just phrasing, but I believe that pronouns connected to a preposition, in any case, ALWAYS have a н added (if it starts with a vowel) to the beginning. Note,third person pronouns are the ones that do this, in order to distinguish between the possessive adjective, which otherwise look the same in some instances. Prepositional (third person) pronouns all start with н since they always come with propositions. Coincidence, I THINK NOT.

I dont know if you want to note this, but весь's (apostrophe s on a foreign word...Wow) different forms change between an adjective and a pronoun. When with a noun, it means "all" or "whole". When on its own, все is everybody/everyone, and declines like an animate noun, which distinguishes it from всё-- everything, since....Sadly.... People dont write ё anymore.
