I hear ya!

Sometimes pain is overwhelming and leaves no space for anything else to exist.

I found that there was a zone just shy of that where pain and reduced functionality in the tasks of everyday life meant whatever energy I had available was devoted to getting through each day. But I didn't count that as being non-creative. I was as creative as ever, it's just that all my creative efforts were directed at just that - the everyday tasks of living. When you can't do things the way you've learned; the way 'most everyone expects you to be able to; it can take an enormously creative effort to keep life running. I don't know about you, but I figured out some truly amazing ways to eat when I could barely shop for food, had minimal ability to prepare food the ways I'd done before I was ill, and was struggling to approach the whole thing through waves of nausea that almost dropped me to my knees. The solutions I arrived at were CREATIVE, dammit! No-one ever showed/told me how to do that - I figured it out for myself.

I also found that my major release from pain was in dissociative mental states. (Something I'd practiced long before I was ill, and overused in the early stages - I had to learn to use appropriate pain relief systems other than my mind - but I still often simply go somewhere the pain isn't in preference to taking painkillers.) This meant that often I could leave my body in a foetal position on the bed (or somewhere else safe), and spend time in creative mental states. Bringing what was in my mind out into public view was another matter, of course. Loss of motor control and hand-eye coordination made that process frustrating, but over time I closed the gap by developing techniques that were less physically demanding, and by getting better. I realise that both options aren't avaialble to everyone (at the time, I didn't know that getting better was an option open to me), but doing what's possible... and the discovery process whereby we know what that is - it may not be easy, but the alternative is worse.
