Dear diary,

My sister visited today. Well, she tried to. I didn't let her in, she could have the sickness. It could've been a trap.  I couldn't risk it, I can't get the disease.  I can't become one of them.  I just can't, I'll lose me, and I'll do horrible things.  Maybe my sister will cure it, she's a doctor.  She's smart.  Hopefully it's not too late for me by then.  I'll know when it happens, if I'm still me. I have to be, I can't get the illness if I'm locked in by myself.

Love,
Elenora
