Fleury, do you have a relative or at least one friend/acquaintance that you can talk to in real life? They would be able to tell you more about your behavior and why you get labelled "creepy". Being online we can't see you or judge your mannerisms to see what seems "off" or not?

If you suspect how you don't look at people might be a problem, check it out. Practice looking at people when you talk to them? Start with people you aren't too worried about, store clerks and the like that you won't necessarily ever see again. Do you have a supervisor at work? Can you ask them how you come across to other people and what the supervisor might suggest to improve your behavior/work relations?

If you have three eyes or some other gross physical defect or something, that might frighten others (their response/fault, not yours). If that is the case you might have to deliberately talk about it with another you wish to befriend and let them get to know "you" and your interests and get past your physical looks.
