What an interesting discussion! I'd like to sing along.
I wrote about this recently in my writer's block subforum thread. In my case, I called it a crisis of confidence rather writer's block per se, but the results are the same.
Interesting stuff on meditation and self-sabotage, Old Hack. I pray the rosary (which involves meditation) and would think of your posted thoughts as counterproductive cognitions (from my training as a cognitive behaviorist), but it ends up in very much the same place. That sort of thing gives me hope. Truth is still truth no matter how you come to it.
I tend to try to power my way through internal distress. For an unfortunately large portion of my life, allowing myself space to cope hasn't been a viable option. And quite often it works, at least for me.
But eventually, something will happen that I can't power through. And then I'm screwed. I don't do well when I feel trapped. That's an overwhelming trigger for me. And then I'm trying to function while I'm screaming inside. It's exhausting.
So, lately I picked up a virus (known in southern Oregon as the Charleston Crud--it couldn't even have the decency to possess a dignified moniker). I spent much of February and March in bed. This is truly devastating for me--to be physically compromised for this length of time. Even today, my physical endurance isn't what it should be. I'm trying to power through that, too. Work (at construction or gardening) a half hour, then sit until my heart rate normalizes and I think I can put in another stretch. I don't know yet how productive this will be, but I don't think I'll build physical endurance flat on my back.
I've got personal family challenges that appear un-overcome-able, at least for now. I went to counseling to check on it, decided that yes, my judgment wasn't skewed in this area, and so now I'm trying to leave it in the past. To deal with it more if necessary when the wound isn't so raw, and hopefully, when I've grown and developed more perspective.
My main writing problem is that I'm attracted to self-publishing for a variety of reasons (the ability to use my own visual art in my covers, greater control, and the general mindset which is quite similar to one I already understand as a small business owner). The downside is my inability to assess that which I don't know--how big a difference would editors in trade publishing make? Okay, I can hire an editor. But I'm unsure if an editor who wants to gain a piece of the SP market is going to be as direct as they might otherwise be. All the incentives in that area seem to be pointing the wrong way. And many editors are out of my price range, and the one I hired in the past proved to be disappointing--less thorough than a beta read.
So I was going to go with beta readers who are also writers (most of whom come from the SYW forums). Then I asked a blogging friend if she would be kind enough to give me a few sentences as an author blurb on my novelette. The piece had already been beta read and liked by several others. I thought it was done. But my friend really was kind. She told me it wasn't ready yet. And looking through her notes, she was right.
And then I collapsed. I couldn't write. I couldn't trust my own judgment. Referring to Vicky's image, I couldn't tell if I'd passed from the good taste but insufficient skills stage to something of professional standard, at least not with my novels. (I figure my short stories published by outside presses and ezines should pass, objectively.)
So I'm trying to give myself space while still being productive. I'm using my blog mostly to cross-promote with interviews and book reviews. That'll at least help other people and keep my blog going. Social media (Twitter, Pinterest, Facebook) otherwise has withered to just enough to keep my presence from being abandoned. I'll take my friend's critique of my novelette (which wasn't destructive by any means), incorporate it, and find another beta reader whom I can trust to be honest. I mentioned deconstructing Tolkien as a possibility as a forward-motion project, and AW Admin was actually kind enough to say we might be able to expand that into an AW-wide project. (Trying not to hope too much on that one, but it's hard not to since it would be so severely cool.)
So I guess my advice (although I'm wary of dignifying it with that--I'm not sure it's working yet) is to keep moving on something related. Don't let it paralyze you because inaction feeds depression. Exercise. Get counseling if needed for other areas of your life. And don't beat yourself up if you're truly doing the best you can.
