I have a concert and im going ot mess up...?

I play saxophone, and I dont know what to do. Im going to a concert June 10th. I have this song, its my VERY 1st song and im playing solo infront of over 200 ppl. I dont know this one part cuz it goes soooo fast. I've been trying for a week now and I havent got it and im getting really fusterated. Im not sure I should go to the concert, besides they'll be more concerts some other times,right? and my mom is like trying her best to support me, but it seems like she thinks im the best saxophone player that I can just learn it like that. i know she means well...but. she I go or not....please add some advice I need it.

and I have REALLY bad stage fright, when I play in fornt of ppl. I just forget how to play the saxophone.

Well, first of all what u should do is when ur practicing is slow down the rythm, and once u do that u might find that its not the speed thats the problem, its just that u dont know how to play each rythm slowly, so if u can play it slowly, u speed it up little by little by little until ur in regular speed. But u cant rush the progression, when i say little by little, i mean get it right 10x's and THEN go a bit faster. If u still dont know how to play it slow, then ask ur director for help with the rythm...As for stage fright, who r they to judge, i bet at least 99.9 percent of the audience couldnt even play in the band let alone do a solo...dont back out, stay with it! Hope this helped...
