Restore from backup deleted 80% of my messages and other stuff?

Currently on an iphone 5 with ios 6.1.4. I restore from backup on itunes hoping it would restore the pictures and apps i've deleted in the past. But when it was restored, half my current messages were gone and other personal stuff to the date which i last backed it up, which was september 28, 2013… So what i'm trying to say is that, from that date until today, almost everything was deleted. I don't understand, it was just a restore backup. Can someone please help me? Is it still possible to get the deleted stuff back

No the restore did exactly what is was supposed to…
