BB Torch :: 9800 Is Stuck On Black Reset Screen?

I have had my blackberry torch 9800 since march 2011, so that's 7 months.

while downloading bbm music earlier, just as it was finishing downloading, my phone switched itself off, and went to the black blackberry screen with the white loading bar at the bottom. it has been in a loop on this screen for about half an hour now, and i am very worried! the white loading bar gets to about 3 quarters of the way done and shuts down and starts the process all over again. i've tried taking the battery out, putting my phone on charge and nothing will help it!
