Xiaomi Phone Suddenly Stopped Working and I Urgently Need Help

My Xiaomi phone suddenly stopped working out of nowhere. It won’t turn on at all. There’s an earthquake happening here right now, and no one else’s phone has any issues. If something happened to me, I wouldn’t be able to get help. I’m writing this from a relative’s phone, and I’m urgently asking for assistance. How can we solve this issue? Please help. I repeat, there’s an earthquake happening here, and another one just occurred. I have a baby with me, and my phone is not working—if I were trapped under rubble, who would be held accountable? Note: My phone didn’t suffer any impact; it stopped working suddenly. I urgently need help. Even as I write, aftershocks are happening. My phone needs to be functional so our loved ones know we’re safe.
