Why do my apps and downloads keep quitting on me?

[AC Question]

Yesterday my Droid turbo started force closing the gallery app instantly, Facebook stays up for a minute then closes without any warning, and none of my apps will update or allow me to download stuff. The downloads and uploads just keep restarting over and over again. Also my message + app will close with out warning as well. My phone still has 3 gb's or so of space left on the hard drive so it's not full. I've tried restarting my phone a bunch of times. Anyone know what's going on Here?
