It's an interesting question. You are yourself, but you have a disorder. The thing is that sometimes we don't know if things we do or say are just normal or something influenced by disorder. I haven't figured it out. Today I found out that the way I feel when I go out and around people is anxiety. Well hello! I thought all this time it was just my introverted personality. I've been on meds for anxiety for about a week and am about to go out AT NIGHT to a function where people will be and I'm not nervous. That has not happened in at least 5 years!!!
All and all, I am me, but I am bipolar too. To me this means I'm different than the greater population in ways that effect nearly all aspects of my life. I'm just rambling at this point, or thinking it out loud. I understand where you are at and why you ask the question. While I still don't have the answer, I know it doesn't worry me as much as it used to. I suspect time will be good for you too.
