I Am a Sensitive Person

Its not really hate but its just ive always felt since a ling time ago that im adopted !!! We dont talk much. We dont dress like each other , eat like each other , dress like each other and we really dont have the same taste in ANYTHING !! Whatever i do its always wrong because they do it in a different and odd way and therefore im always the ugly duckling in the house !! If i ever decided to talk to them a bit about my life , my brain will always tell its a bad bad idea to do so !! They will take what ive said. And use it against me when we fight and just crush me down to earth so ive built this dark facade around my self and shed an armor so NO ONE can get inside me and as the time goes on , this dark facade ive built is consuming my humanity and making me a cold hearted bastard yet i know that im extremely fragile from in the inside !!
