Opinions?

Ok, I`m only 13 and my mom wants to start buying dresses and inviting people to my Quinceanera. Now, she`s not inviting them by saying, "Come at this time, date...". She`s just asking them to come. I think that she is counting her eggs before they hatch. She already has about fifty lists of things she wants to get, but we don`t know if those things are going to be available two years from now or if I`m going to like them. Right now, I think my mother should be trying to save money, because at this moment, she has just about everything figured out, but no money saved at all. I`m worried that when it`s time for my Quinceanera, we aren`t going to have any money for it. When I try to explain myself and my feelings to her, she gets all mad and says that she`s not going to give me a Quinceanera at all. I`m all for trying to plan things and pick stuff out, but not the things that I`m not sure about. I really don`t know what to do, and I`m tired of fighting with her. She is completely osessed with my Quinceanera and that is LITERALLY all she talks about every hour of the day. She totaly zones herself out of reality and just stays on the computer looking at Quinceanera stuff for hours on-end. Maybe if I show her your guy`s opinions on this situation, she`ll understand what I`m trying to tell her. Please, please, please reply with your opinions on this matter, I thank you for you time.
