I don't know that I agree with everyone who says they are or have been a difficult person... but that's just me? I figure you're talking about how the general populus considers you (me?) That wouldn't be a term I'd consider for me. It's a very heavy label, imo.

It has always taken some ppl more time to get to know me than others, but each one who did so said it was worth it. Now, I'm high maintenance, mainly due to my ...the way I am from the injury...

Rough edges? Sure. I used to take everything personally, as I am a sensitive person and care very much. I had trouble explaining myself to others. In fact, I stayed at psych central to "use" it to hone my social skills, which had diminished due to my isolation. I think I'm doing fairly well on this now, but need more "teflon" perhaps.
