I'm going to yank my hair out!

My crackberry has always been extremely well behaved and I love it, dearly... too much almost! But as of late it's been deleting EVERYTHING! And I am a text-a-holic! This is killing me. I forget to back up those precious ones and then I look and they are gone. 

HELP! Do I need to get rid of these aps?! Isn't that the point of the damn high-tech phone?! I am so upset.
