I know I'm jumping in very late, and I don't intend to make a whole lot of comments here. Let me just say, Syler, that the frustrations and isolation you're describing are really common in the GT adult population, particularly the men (I can think of one respondent in my dissertation research who was in a *very* similar situation to yours and had very similar life experiences). (You might try reading Barbara Kerr's book on smart boys / men... I haven't read it yet, but her work on the female experience of being GT is pretty interesting.)
My dissertation was on the experiences of gifted folks in psychotherapy (
http://www.davincilearning.org/sketchbook/research.html), and what was really sad was how many folks described psychotherapy experiences that merely recapitulated the isolation and misunderstanding they experienced in the rest of the world. However, others described therapy as having been extremely helpful (often they were the same people, who had had some rotten experiences and then some terrific experiences, which was nice, because it meant that I could answer critics who said, "maybe these clients are just narcissistic jerks who can't form decent therapeutic relationships with anyone.")
Okay, so I'm well on my way to being a Real Live Shrink, so I think that psychotherapy is a fine and dandy thing that can help a lot of people. I see a therapist myself, no shame in it. You don't need to have something "wrong" with you -- there are entire schools of psychotherapy (most notably the humanistic and psychodynamic, which are where I like to spend most of my own time as a therapist) which emphasize just understanding yourself better as you make your journey through life and exploring the world of relationship with someone who is safely *not* directly involved in the rest of your life.
For that kind of exploration (as opposed to short-term symptom relief and coping strategies and such, where any good listener was sufficient), what I found in my research was that it really does help for a gifted person to have another gifted person as a therapist, and for that therapist to have really done a lot of their own work about metabolizing their own cultural experiences of being GT in a world that is not really made for us (some of the nastiest screwups have come from GT therapists who appear not to have done that work and thus lash out at the GT clients).
I don't know where you're located, but perhaps if you post a general geographic location, someone will know someone who has been helpful to them or to someone they know.
