What can I do?

So I am different then most people. Sometimes I do random things like say the first thing that comes to the top of my head or something really silly in public or at work and some people laugh. Then there are those people that always have something to say. Maybe it's because they don't understand a person like me. Maybe its because they don't agree with some of the things that I say. I don't know. I am not here to make other people happy but sometimes i cant help but feeling like i have 2 heads or something because of the way people look at me. I am not going to change because i have been like this my whole life and it fits me. I am different and unique and I wont be defined as a type of person by anyone. But I do feel left out sometimes and I really wish that people could except me for who i am. I used to be that girl that had low self esteem because I had no friends but then as I got older I found that it takes a very good and loving individual to deal with me and that's OK. Because as long as I don't have to many friends I will never have to wonder who my real friends are. This song says exactly how I feel right now.
