Doubt.

It's strange...sometimes I feel really confident in my writing ability, like it's what I was meant to do and that it's very much a talent. Then there are times like this, where I don't feel anywhere near good enough for anything, and curl up in a ball of insecurity and self-criticism at the mere hint of someone else being a better writer than me or disliking something I've written. My writing might be something that comes effortlessly to me, but it's so fragile. So fragile.
