vocal depression

A state of low faith in ones voice and/or singing abilities. Known to both start and end suddenly in otherwise stable people due to hyper-sensitivity specifically in relation to singing. For example, off-hand comments regarding ones singing ability can either trigger or end vocal depression.

Naw, I missed that High B yesterday, and I think I'm in vocal depression.

Oh, hey, I heard your CD last night, it was pretty good.
Oh my god, really?! I think you just cured my vocal depression.
