dressing up as a pirate

seriously, going around wearing a teddybear on my shoulder (to resemble a parrot), a sword, and a pirate costume I'd ordered on a manic spre from amazon

then insisting people called me "davy jones" (in the pirate accent, or I wouldn't answer)

question: have you ever believed that you have an illness that you've not oficially been diagnosed with, and if yes, what?
