@rainbowsarenice , Autumn, Does sound like the display under touch screen glass is broken. 1st link below shows how to disassemble to change the screen assy., the second link is to where the assy. can be purchased which you can also do a search on for better pricing possibly. If not comfortable working on your device take into a good cell phone/computer repair shop, have them take a look and estimate repair. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.
