Hey everyone, I'm in the weirdest situation and I don't know if I should tell anyone. Please help me. On Wednesday, my best friend sent me the creepiest message in the world. She asked me what to do if I leave the country and change my identity (fun fact: she sent it at 11 PM). The worst part is she's never texted me at that hour, let alone to joke around. I haven't dared tell anyone. Please help me, give me some advice. I can't even leave the house since I'm sick, and she's not answering her phone or texts. What should I do?
