Do you believe that some people are born with a dark cloud over their head?

I am looked at as peculiar to almost every one who I encounter. I try to seem normal and friendly, but people almost always say "you didn't know what you were getting yourself into". I don't have a relationship with anyone in the family, but then again, none of us in the family have a relationship with anyone. I feel so different. I can't explain it. I had a business for 14 years and I walked away with no friends from it. I put beautiful art of facebook and rarely does anyone say anything about, almost like they are afraid if they say something they too will be ousted. I don't seem to be able to make friends. I can not for the life of me get a date. Have you ever known anyone like me?
