Try giving your depression a silly voice: Donald Duck, Homer Simpson, or Boris Johnson on helium. Let it speak in an outrageous French accent; let it do silly walks like John Cleese or wear a funny hat; let it slip on banana skins.
PS I also collect good jokes about depression. Some of these may be in bad taste but what the hell?
Q: How many depressives does it take to change a lighbulb?
A: (In monotone) It doesn't really matter because the darkness will always win.
If you know of any good ones, please send them to me.
