complex self

I am reading Trip to Hanoi by S. Sontag. She writes about her trip to the city in 1960s (in the war with America). Bob and Andy are persons go with her.

"All I seem to have figured out about this place is that that an American brings to Hanoi. At least this American! I sometimes have the miserable feeling that my being here (I won’t speak for Andy and Bob) is a big waste of our Vietnamese hosts’ time"

I am not quite sure meaning of underlined words. It seems she wants to say she is too complex for people in Hanoi. Is that correct?

A self (n.) is used in the philosophical sense and refers chiefly to a person's mind-set1, i.e. the sum of one's experiences, opinions, and reactions and how everything is perceived in one's mind". It is close to the meaning of the words "individuality", "character", or "conscious personality".

1 OED "An established set of attitudes, especially when regarded as typical of [...] social or cultural values; the outlook, philosophy, or values of a person; (now also more generally) frame of mind, attitude, disposition."

What she is telling you, despite what her words say, is that she has figured out something about herself, not about Hanoi. She is too self-centered to have figured out anything about Hanoi. She is saying that she has many conflicting feelings/ideas about being there and isn't sure what to think about her situation.
