What do you call being proud and yet a bit bitter for somebody?

Okay, so my friend Alexis just passed her behind the wheel and gets her license on Friday. I'm super proud of her, cause I know how much it means to her; I couldn't be as proud as I am for her! However, I'm a bit bitter for the reason of I feel that whatever I say, such as 14 months ago when I announced that I got my license to little to no fanfare, where she gets a ton of fanfare. I swear, some people get all the publicity for the same thing as I do, and really, that kinda pisses me off. It's like the world stops for certain people while it moves on for me. I don't want to spoil the mood, cause I know it's monumental for her, but at this point in life I'm starting to get a bit tired of being vastly underrated over the same things as other people.
