Hey there Criseal,
It sounds like you are unable to get your email on your iPad suddenly. I'd recommend these troubleshooting steps from the article found here, named:

- Log in to your email provider's website to make sure that the account is active and the password is correct.
- Make sure your settings are correct using Mail Settings Lookup.
- Restart your iOS device.
- Delete the affected email account from your device.
- Tap Settings > Mail, Contacts, Calendars.
- Tap the affected email account.
- Tap Delete Account.
- Add your account again.
Thank you for using Apple Support Communities.
All the best,
