@cheyenne884 , Cheyenne , Check out the links I have posted showing how to repair the screen yourself Link#1, and depending whether you need the LCD or just the glass can be had through iFixit store(always ensure part is correct for your device prior to ordering). If really not interested in making repair, last link is Nintendo support where you can inquire about repair or do a google search for a good shop closer to your location. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.
