I am inclined to see you more as a 4 than as a 6, though I am open to either possibility.
Be careful when soliciting advice about 6s--there is a trope going around on the internet that "6s just don't know they're 6s", "they can't admit it", and "all 6 descriptions are bad". I know this is at work, because I fell into it myself for about a year. I couldn't figure out my core--4 and 5 seemed to fit my problems the most, but so much in 4 descriptions is...very unlike me. So, following online advice, I typed as 6 and then just became uber-frustrated that the enneagram seemed so applicable to everyone else...and yet, it did nothing to explain who I "really am" (which, in retrospect, is so laughably 4ish that I literally cringe to think about it).
In the end, Stansmith, you're just going to have to do what I did--look at your motivations. Look at the surrounding types--you should see those motivations at work within yourself as well as those of the core type. If you're a 4, you should see the 3-4-5 motivations in a line. If you're a 6, you should see the 5-6-7 motivations (Don't go by behaviors; strip it down to the core motivations).
Anyway, I wanted to tell you that because you seem to be having the same trouble I did--I didn't see myself as "sensitive" enough to be a 4, not "emotional" enough. I can't relate to being "effete" or "refined" or hell, even "too depressed to get out of bed" or whatever things are "supposed" to define 4s. Instead, I've come to the conclusion that core 4 BEST describes my core psychology and struggles in life. Not every word will fit perfectly, and that goes for you, too.
And as a side note:
Yes. I suck terribly at Fi. Having all of those rigid values and extreme self-awareness would make my heart implode and explode my head off!
What I don't understand is how they CONSTANTLY think about what they believe in. I do this sometimes, but they never quit.
LOL guys, wow. I'm likely Fi-dom, and that's about the reason I thought I was Ti/Fe at first. "Rigid values" seem unrealistic and confining to me! I don't know WTF I "believe in" half the time! It's more like I take pleasure in feeling out what things mean TO ME, and how that might fit into the Grand Scheme of Awesome that I want my life to become. Others have already articulated the ins and outs of this better than me.
Though I admit, my extreme self-awareness sometimes makes my head want to explode as well!
