The philosophical ramifications of external versus internal perception

Tonight I was told, for about the zillionth time, that I am intimidating.  In this instance the description was used as a compliment, but that hasn't always been the case.  I have been told by a relatively large number of roommates that they found me intimidating, even to the point of frightening, for months of living together.  Bishops, friends, and people I hardly know have all described me this way.

This phenomenon is fascinating to me in a very weird way.  I do not feel intimidating.  I do not think of my self as even slightly scary.  On the contrary, I think of myself as the person being intimidated and the person who is afraid.  I spend my life oscillating gently between anxiety and awkward confusion.

My friend tonight tied my aura of intimidation to my utter lack of bothers given, my confidence in my self and my own decisions, and even the way I carry myself.  Bless his heart.  I guess that does imply that I'm not losing my eternal battle with my posture quite as badly as I thought I was.  But aside from that, the rest of his explanation is a pretty constant theme from others I've spoken to.  People tell me I brook no nonsense and put up with no bullshit.  They tell me I'm confident.  So many people tell me this.

I, on the other hand, feel like I am a person who will accept rather a lot of both nonsense and bullshit.  I mean, I like to say that I don't put up with it, but it is one of those "say it and maybe it will come true" situations.  And confident?  I question pretty much every decision I ever make.  Endlessly.  It is exhausting.

So who do I believe?

That I have these feelings is significant.  I create myself, and my thoughts and feelings are the molecules I use for that creation.  I can't exactly experience life any way but the way I experience it...if that statement wasn't so recursive as to implode on itself.  Basically, to see myself as a particular kind of person is to be that kind of person.  

But at the same time, I must distrust my own opinion of myself.  I've talked about my struggles with self-image and confidence and self-love.  I know that I am a sufferer of mental dysmorphic disorder (which is a thing I just made up) wherein the image I see in my mental mirror is not necessarily accurate to the truth.  I'd like to think that there is an intrinsic me that is independent of my awareness and opinion of it.  But are the opinions of the people around me the way to discover that immutable part?  Does the constancy of the feedback lend it credibility?  I suppose it must, at least to some extent.  

Do I want to be intimidating?  My friend told me it was a good thing, and I do strive to live my life accountable to no one but myself--successfully or not.  But shouldn't I be able to do that without frightening people?  

Another friend once told me that he would rather intimidate people than risk not being taken seriously.  I'll admit, there is a certain gratification in knowing that people so far from seeing your insecurities, see the reverse.  But I'm not sure that I agree with my friend.  That is, I certainly wish to be taken seriously, but I don't think that intimidation is the only or even the best way to achieve that goal.  And while I do like to believe in that immutable core of the self existing independently of the conscious and reasoning mind--which sometimes perceives inaccurately--somehow I also believe that that core is capable of change and growth.  Or at least, I can change the way I express it.
