I've been thinking about this & really, "who I am" meaning who I see myself as is only that. No one else has the same picture. To some people, I am strictly hostile. To others I'm calm and kind. I'm weak, funny, strong, lame--I'm a thousand different people depending on who you ask. The truth is I'm all those things and a thousand other things that no one knows, depending on the situation, the past, the present. I felt bad at first, not being able to "define" myself. Reality is, I don't ever have to. If I was only calm and caring, I'd never speak up against people who don't appreciate me/never defend other people. If I was only hostile, I'd be a really crappy person. How do you define an entire person? I think that diagnosing you as borderline or antisocial based on a vague thought that we all have is irresponsible.
