Why doesn't anybody wanna talk to me anymore?

I LOT of people keep telling me that I brag WAY to much. I don't! I would tell them how I got and A+ on my spelling test as a kid a lot and how much of an actress I am. And I sing, and I have superb language skills AND have high levels than anybody else In my special ed cl. I would tell people, but they just ignore me. I would repeat until I get an answer, like I told one of the girl from HS, "I can sing! People tell me how much of a great singer I am! Isn't that awesome?" and she didn't listen to me so I said, "Isn't that awesome?" like 20 times until she finally said, "I heard you!!!! Stop it!!!!" WHY WON'T ANYBODY LISTEN TO ME ANYMORE?!!!!
