Is it possible for everyone not to like one person?

Okay, let's just state for the record, something is certainly going on here. It doesn't sound like everyone does not like you, something about you is causing them to take note in such a fashion that it's causing you concern. If I were you, I'd ask a friend or relative whom you trust to be very honest with you and tell you what they think it is. Why not upload a photo of yourself, just the way you dress in everyday life and ask yahoo viewers to see if they can help narrow down why you are getting the response you're getting. You say that someone stated that you are the coolest and nicest person they met, so maybe it's the way you are presenting yourself.
