1. Having trouble deciding what is right and wrong, or with decisions and plans in general, constantly searching the different perspectives of things.
2. Hating and loving things about yourself at once or constantly alternating, often the same things have deep conflicting viewpoints
3. Not being able to connect to people or get what makes them tick or feeling like an alien pretending among them

edit - I also have the gender issue... but I have no idea if that is because of being borderline. It definitly makes me curious. As a child I would prefer to play the male role in any make-believe, and it is a perspective I continue to prefer when storytelling/writing. I get sort of bored of the female role? Hah... well, again, no idea if this is borderline or just some childish fantasy.
