Сонсголыг хуваалцах

My doctor said: You don't exist. I went for a checkup. He looked at my file confused. He said: I have no record of you. Ever. No birth certificate. No medical history. Not in any system. I showed him my ID. He said it's fake. I called the government. Same response. Nobody has ANY record of me. Last week I tried to buy food. The store wouldn't take my money. Money from a non-existent person. Now I'm invisible. But I'm still here. AITA for existing when the world says I don't?
