Will and how can I get my scream back?

My scream, not my voice, is gone. I'm a cheerleader, so of course I need to be loud. I mistakenly used my scream instead of my diaphragm. Ever since the first game, which was the second week of school (its the second semester now), I'm still don't have my normal scream (I had one of those really high pitched screams that you only see in movies). So does anyone know if I'll ever get my scream back?
