My love/hate relationship with personality typing...

I have always thought I was an ISFJ. I think my parents typed me as that when I was younger and I pretty much always test that way, but some things don't add up for me. I am not tied to traditions the way ISFJs I have met are. I always thought having Si as my primary function made sense because I derive so much pleasure from my memories and enjoy reliving them in my mind. But I am more free flowing in how I process life than ISFJs I have met. I feel like if I'm an ISFJ, I'm a very a-typical one. The difficulty is that I can relate to the type descriptions for ISFJ, ISFP, INFJ and INFP and have tested as each at various times. I know I'm neither an ISFP nor an INFP. Most of my closest friends are intuitives. This seems odd for an ISFJ. One of my biggest issues in figuring out my true type is that I don't really understand intuition vs. sensing. I don't know if my level of intuition is intuitive enough to count. And yes, that probably seems silly. I just know that I feel a lot more like INFJs get me than ISFJs do.
