Bookcase, I was thinking about you in bed last night (not like that!!) This may be old news to you, but anyway. I get stuck with my hopelessness and my inner bully whenever I feel I have to 'do well' - that is, when I'm coping. My mechanisms for being okay (successful, even) are all based on self-criticism and negativity; expecting the worst. In terms of compassionate thinking, I function "best" when in the fear/protection state and do not, yet, know how to function any other way. The adrenal overload, from being constantly in fight, flee or hide mode, wears me out and I end up wanting it all to stop.
I'm a long way from being recovered yet - in fact, an outsider might say I'm going backwards - but am quite pleased, personally, with the fact that I now spend at least part of each day feeling content. And my thinking has changed, dramatically, since the first years of my illness. I'm fairly optimistic that I will achieve a full recovery - by my definition, this means being able to function contentedly and free from self-hatred. I'm learning that the way forward is to stop fighting the illness.
Mumsnet, especially these threads, has been (is) a powerful assistant. Here, I'm allowed to feel weak, confused, lost and helpless. And I am not allowed to hate myself - there's a steady supply of gentle encouragement to like, love and be kind to myself. My first therapist was good at this, too, and she's the one who made the most difference.
There are books and CDs which express this better than I'm doing now; hopefully someone else will come along here and express it in other terms as well. In a nutshell, what I'm trying to say is that perhaps you need to love yourself just enough to let it all go - allow yourself to be ill, damaged, down, sad, broken, empty, etc. Let yourself sink and have some compassion for the hurt you feel.
There's a Pilates method for relaxing the head, neck and shoulders, in which you lie on your mat and let the floor take the whole weight of your head (10lbs, if I remember right). The instructor asks you let your head 'sink through the floor'. It's surprisingly hard to do. We are so used to carrying constant tension, we hang onto that weight even when we know the floor can carry it for us. People in our situation carry our burdens just as tenaciously.
I don't know about you, but I'm so attached to my burdens of blame, fear, etc, I can't let it all go at once. It feels as if I'd become a pile of jelly without the tension. Experience tells me now, though, that letting it go for a bit - and letting a bit of it go - allowing myself - is what lets in the healing.
