What should I do about this problem!!!?

Ok, so i'm in athletics with some pretty mean coaches. I got hurt during cross country season, so i sat out the whole season. Well, when I wasn't there, the coaches ped out sweats for cold weather, and i didn't realize it till the middle of basketball season. Well, i'm really shy so i didn't want to ask for some sweats but we start track tomorrow and it will be really cold and i'll need some. But i'm afraid if i ask they'll be like why didn't you ask earlier and give me a hard time and make a big deal about it in front of everyone, and i cant handle that! I'm too shy! What should i do!? What should i say!? Someone please help!
