Grandmother help?

I am 20 yrs old and my grandmother has nothing to do with me. There are 7 of us grandkids 3 that 3 has paid their way through college, one bailed out of jail (scary i know haha) and has given some here and there to the rest, but she wants nothing to do with me, and she never has. She even spelled my name wrong on my b-day card. and its not a hard name trust me. And i dont know what to do, i cant talk to her bc she immediatley will start defending her other grandkids and telling me i am wrong.
