Really? How very unusual for a Gemini to want his chart done! ha.
I can see in your chart you have an odd mix of belief/feeling and intellectual expansiveness/originality but still, I thought the Gemini skepticism would overrule all that! hmmmmm. What do you mean you don't know who you are? There is only one planet in the 12th house (it's hard to see what's in there - it's your moon/mother/nurturing thing/mothersLove - I'll tell you about that later) But, I guess you may be referring to the duality that are Gemini's? They are one thing, then the other...flipping back and forth...seeing the world in a relative way - not in an absolute way. That's one of the symbols in the Gemini/Sagittarius axis: Relative/Abolute Ideas for the sake of Ideas/Gathering the ideas into a Philosophy. hmmmm...
I see your poetry planet too (that's seperate from the intellectual Grand Trine you got goin' there) - Mars in Pisces nicely connected to your empathic Cancer Moon (but there's some hurt/sensitivity there)
Anyway...I have a few charts ahead of you...but if you want to email me at ilsa88@excite.com I *will* get around to giving you some information if you're really interested!
