All of my Notes are gone after updating the ios 9 and I dont get notifications when I receive texts?

I updated my iPhone 5s to the lartest version of ios 9 and everything is messed up. When I go to Notes it says that I have zero folders. I haven't updated Notes yet. If I remember correctly, the first day all the notes were there. I backed up my phone before updating buy apparently I had notes off for backup so iCloud isn't a solution to recover it. What should I do, how can I recover my Notes. The same thing keeps happening with Reminders but it recovers after I turn off my iPhone then turn it back on.

Another problem I had is with messages. I have all the notifications on for messages and I turned it on and off a few times but it didn't work. So the problem is that I don't get notificatins when I get messages. The only way I see it is if I go to the app and tap on the person who sent it. But after I leave the app then enter again, the message that was sent isn't there anymore. Please help! This update ruined my phone and there are so many problems with it. Thanks in advance!
