Here's the thing. I have suffered from breathing problems all my life (literally) and fairly severe allergies for most of it. Between these and the medications I take to manage them, I spend much of my life feeling like I'm walking around in my sleep. Add to it, some other crazy health issues, pretty severe SAD the past few years, and a neurological sensitivity to ions (I think), and pretty much everything I do suddenly requires effort and concentration -- neither of which come easily when you feel like you're walking around in your sleep.
Consequently, when work keeps me busy and other things in life get crazy, I end up mentally and emotionally crashing. This leaves me little time for my writing, or for the things I want to do affiliated with my writing (such as this blog, and following of yours).
Sometimes there's an extended period where work is slow and I still have mental and emotional energy at the end of the day. That's fantastic.
Sometimes I leave the region of the country I live in (and to which I am most allergic) and I get a a two or three day window where I am productive *and* creative all in the same windows. That's amazing.
Most times, I just wish I knew how to write in my sleep so that when I do crash, I can still go on with something that I earnestly believe is an important part of who I am.
Of course, I feel like I half wrote this blog entry in my sleep, so I'm not quite sure I did it.
