I have a flight in 2 days and I’m panicking. PLEASE HELP.

My phone was charging and I was on Instagram when the screen blacked out. I pressed the power button a couple of times, but it wouldn’t turn on. I unplugged it and tried long pressing the power button, and eventually doing the hard reboot (power + lower volume buttons) for more than 15 seconds, but it still wouldn’t open. Lastly, I tried the hairdryer to the back of the phone (to heat up the battery?) but still nothing.

My phone is about 18 months old and I’ve never run into this issue before. 0 issues prior to this. It was working perfectly. What do I do? What else can I try? Please please help. 🙁
