Why Do So Many People Want To Alienate Me?

It seems that as far back as I can remember I get alienated by other people. I was never invited to parties in high school or college. At work if any of my co-workers threw a party our outing I seemed to always be excluded from the invitation list. Since high school I had only a few friends, but they were relatively close. As they got married one by one I found myself alone. Now, being an introvert I am quite comfortable being alone, but still the reaction I get from total strangers seem odd. When I am out and about I have found that a simple friendly smile is met with a cold hard stare. Just today I went to a grocery store. I noticed the check-out lady was smiling and friendly to the customers before me but when I was her customer her attitude turned very cold and unfriendly; almost to the point she was in a hurry to get me out of there. I get this type of reaction from at least 99% of the women I meet, not so much from the guys.

I do practice good hygiene and am clean cut without tattoos or piercings. I have been told that I am a friendly sort of person with a good sense of humor, and have a very self-confident aura but still I get alienated or have people just respond with instant dislike when they meet me. Could it be something physical? I have no deformities but I am only 5'7" with blonde hair and blue eyes. I have been told that these physical aspects are usually found displeasing by women.

Does anyone have a clue as to what I might be doing to attract this negative reaction?

It could be some thing physical but in a positive way. You mention that you are 5' 7" tall, blonde hair blue eyes. Women are actually quite attracted to these types of people. Maybe you are better looking than other people. Only like 3% of the world is blonde hair and blue eyed I believe (could be slightly more). So I think that when people come across those types of people they like to look at them more. Like a jewel. Maybe women are intimidated because they think you are cute or something?? I struggle with this as well. I'm 6' 4" tall, blonde haired and blue eyed guy. I always think people are looking at me for negative reasons. I find it hard to look at people in the eye because I think I will scare them. I think that people with will think I'm crazy if I look at them in the eye. I always think I look at people wrong. I'm 23 now and it's only gotten worse. I feel like I am the one who alienates myself not other people. I just take everything a little more negative and I hate that. I myself actually have a physical 'deformation'. I have a rather large port wine stain birthmark all up my left arm from fingers to shoulder, chest and all. I find that people are quite turned off by this. Everything has to do with the way you think about these situations while you are in them. So I guess try to be more positive about these encounters. I'm really struggling with this day to day. I hardly go out because of this..
