What can i do to fix my BlackBerry Curve 8530 (i think 8530, can't find my box)?

When my phone died, I let it restart.
But when it turned back on, my email icons were gone and even if I go to my email options, delete them, and readd them, nothing happens.
Also, everytime I reboot my phone, a message saying "uncaught exception: index 23 >= 23"
And I can't get to my picture folders without it freezing.
I've taken out my battery, left it out, put it back in a million times. What do I do?
