I can kind of relate to this. I do wish I could be comfortable enough in my own skin to be unabashedly myself. For as long as I can remember, I've been receiving the message that I'm not acceptable as is, and I need to change to be more acceptable to other people. This has been my experience since early childhood, thus I don't feel very in touch with my real self. I just barely know who I am, but I understand enough to know that my real self is quite weird. Thus, if I were to allow myself to be fully myself, I'm sure I would be quite weird, even weirder than I already come off without meaning to.
As it presently stands, I really have no clue how to be my true self, as I don't even entirely understand who this self is. Moreover, a lifetime of bullying, ridicule, and being told time and again that I need to change to be acceptable to other people has left me with a rather powerful conviction that I'm a substandard breed of human, and I'm just not as important as other people. I have not yet figured out how to get past this conviction. Thus, I can't help but feel that I can only be acceptable as far as I can please other people. Since I'm quite convinced that no one really wants to be bothered with me, a big part of this entails making myself as unobtrusive as possible.
I do try to do my best impression of an NT when I'm in a public setting such as my job. Based on other people's reactions to me, my attempts at playing "normal" are often unsuccessful. Thus, I find myself trapped in a cycle of trying to act normal among other people, and never quite making it. It tends to be a rather uncomfortable way to live. If I can't do a convincing impression of a normal person, I suspect I would be happier if I could be my real self among other people, as weird as that self may be. I'm pretty sure my real self would be regarded as quite creepy by others, but that's beside the point.
