iPhone 5 not accepting apple ID password

This afternoon I suddenly stopped receiving my text messages, my email wouldn't update, Instagram, web browser, everything said I had no internet connection despite being connected to Wifi and having full LTE when not connected. Then, my phone started asking for my apple ID password and when I'd type it in, it'd say it was incorrect. I've reset my password twice using my MacBook, still says incorrect on my iPhone. I tried doing a reset on my settings and just ended up losing contacts from my phonebook 😟 I don't know what the issue is and I'm annoyed and frustrated and I can't get apple support on the phone for another 6 hours (and that's if I wake up at 3am). I have a flight tomorrow and I'd really like to have my phone working before then. Anyone?
