I spread the disease because there was no cure
That's a horrible thing to do. Did you enjoy spreading the disease?
I like it. It's exciting and fun.
It is not good to want to spread a disease because you feel helpless, you should get more opinions to see if somebody else can help. Otherwise you might die.
I am already a vampire so I can't die.
Vampires don't exist. You need to get medical help and stop spreading what you have.
