I say, you must be one tough cookie. I like that characteristic, my sister is the same way. You're not stand-offish, more assertive and have strong work ethics. You take the initiative to get things done efficiently. Warn you though, don't overwork yourself. People can often be intimidated by someone who comes off as strong or may have jealousy issues. It sounds like your performance is top notch and that may be why some of your colleagues shun you away. I have BP as well too and I believe being a perfectionist is a trait.
