iPad is now severely messed up after connecting iPod to its iCloud account, and after switching to that same Apple ID for iMessage/FaceTime

So, it all started with iMessage. FaceTime had similar log in symptoms as well, but I don't really use FaceTime. The best way I can describe it is with this... Paragraph I sent to my friend, describing my dilemma.

iMessage and everything was PERFECT for about a day, then it stopped working suddenly on my iPad. Then it wouldn't work on both. Then I could sign in on my iPod but not my iPad. Then finally I could log in to both. But it deleted the old send and receive email I was using, so everyone I texted would see an email rather than my name. It WOULD NOT let me add the email again, it would refuse to send a verification email to allow it to work, and would finally just say "error". Now it suddenly stopped working on my iPad and it hasn't worked at all for almost 2 days now. Oh and I only receive notifications for VZ Messages on my iPod, not my iPad. All the settings are perfectly in order on my iPad as well, so I have no clue what to do.

Instagram notifications also have appeared to behave as the VZ Messages notifications have. Any ideas? These are all of my top-used apps, and all of their noticatioms are left broken on my iPad after I added my iPod to my iCloud account, and started using my own Apple ID for iMessage and FaceTime.
