feeling like an alien

I often wonder what is wrong with me. socially awkward and mentally absent from every day events or human engagement outside work.
but that is not resent development of this behavior i always found my self alone having much more fun then with people who often incapable of expressing their own inner feelings. humans are strange creatures they literally cause them self harm by not telling others how they feel. it's like the need to be excepted is greater then the need to be true to one self.
as a child i found that people get terrified of the things i express thats on my mind. so taking up drawing and later painting was my way of throwing a hint without saying out loud what i think.
today i use photography as a tool for this expression. hence the set of pictures telling the story of what's on my mind. they all self portraits
