There's nothing harder than watching someone suffer we extreme pain and not being able to do anything to alleviate it. When all you can do is hug them while they scream and cry. Pain killers having no effect. Lack of sleep driving them to distraction.
For the last few nights I have been woken around the same time to deal with this. It's not only bad for the one who suffers but the lack of sleep for me drags me down too. I find myself falling asleep during the day at the drop of a hat. The feeling of helplessness can be distressing and adds to your tiredness as the pain wears you down too. All you can do is wait for it to subside and provide as much comfort as possible until the sufferer falls asleep and so can you. Some nights it's not worth going back to bed. I make a brew and sit watching anything on the telly to try and numb my mind into slumber. Sometimes it works but not always. Even when peace descends my mind is so active sleep evades me. Pain wins.
