I just Can't Fit in (An Observation)?

Before I explain, please realize I'm not trying to pull a teenage "no body understands me," I'm a level minded adult and I'm asking because Ive dealt with this my entire life, and some clarification would put me a tad more at ease. I'm just wondering if anyone feels a tangible Separation like I do.

Anyway, I've never fit in beyond a very surface level with people around me. I have plenty of friends, a great family, and my life is pretty great despite the usual impediments. But I've always fealt like an outsider, and Ive had to play a role my entire life to get by. I'm always behind everyone on a social level, and I've never connected to any of them.Everyone has their ideologies on what constitutes life, and I'm in a constant flux in terms of how to spend mine because everyone feels I'm no suppose to be how I am. I can do all the right things, fake it 'till I make it, improve myself, whatever, but yet I still don't feel I'm in sync with them on any level. I can sympathize, I can be a fierce friend, and I can be a perfect employer or employee, but yet I fall into the background regardless of the effort I put forward, regardless of my loyalty, and despite my ability to put people at ease. I'm no latent genius, Im not a philosopher, nor do I feel I'm at a superior level of any kind, but I just don't feel like I fit, I'm just going through the motions. Ive observed this since childhood, and it only strengthened well into my adult life. In short, I'm pretty much told I'm always wrong by all sides, I don't take joy in the stuff most others do, and no matter how I excell or put myself out there never find people whom cherish me on an levels beyond your closest acquaintance.

I suppose it's true that INFJ is the ultimate square peg in a circular whole. Once again, it's just a rough description on my state of mind, so any help or ideas are plenty welcome.
