For me it's mostly getting the words out of my head. XD Sometimes I'm too perfect about how I want to present my thoughts in writing -OR- my thoughts just don't come out how I envisioned them and then I get annoyed. XD I also struggle with depression, so when it hits me hard, I have absolutely no inspiration to write. Of course this makes me even more stressed out and uninspired because I feel bad for making people wait on my replies.
