I'm not a bridesmaid??

I got married last year and I chose my life-long friend to be my maid of honor. She too will be married soon but she didn't choose me to be involved with her wedding at all. Because of this I'm a little hurt. What would you do in this situation? I mean, it's her wedding she can do whatever she wants, but I just thought that because we were friends for so long that she would have considered me for something...
