The terminal blahs, which seem such a part&parcel of bipolarMe, really needs the daily disciple of writing--morning pages, if you want to call them that. I started with a notebook under my pillow, 21 yrs ago, & I'd write why I couldn't write that day. I keep it private, because I need the hidden me (including what may not be obvious until days after I've written it) to flow out.
This daily writing attact, over the years, has been therapeutic to the inertia that seems to affect me. I've been able to translate the principle of that to other areas where I never seemed to be able to get from thought to action. Waiting for the inspiration to strike just never got a whole lot done for me--tho of course it kept me entirely in my comfort zone.
