My DP has always struggled to sleep, and his language around this is full of this struggle. I have a suspicion that his way of framing how sleep happens is not really helping him in his struggle for sleep. I don't think you "get" yourself to sleep, it's more like you lie still and quiet and sleep happens. I appreciate that he is struggling with the lying still and quiet, especially the quieting of his mind. But half his brain noise and agitation is about sleeping.
Obviously I am not going to volunteer my insight, because I'm just a twat who has NO IDEA what it's like to suffer and struggle as he does. So I thought I'd share it with you lot instead
