Essentially, we are at our wits end. DF is suffering with chronic pain, the cause of which has been investigated inconclusively. The GP has actually told him there is nothing more he can do, and he frequently makes threats of suicide. He's on morphine, but it has stopped being effective. He is housebound, rarely leaves his chair or bed, and is cared for by DM - however, it's having a massive impact on her emotionally, and she is reaching the end of her tether. The pain can make him treat her very badly, insulting her, throwing things around the room... We live over 4 hours away and have been helping financially with private health investigations and therapies, but can't physically help out, and DB and DSIL are overseas, so in the same boat. If DM can't cope any more, what can we do? She's threatening to walk out, and frankly I don't blame her, but really worried about what would happen to DF. He doesn't want to move here, and we wouldn't have room, or really the capacity to care for him, given our work commitments.
