I am quite prepared for you all to say "beak out" and that is a bit how I feel. But....
A dear friend of mine has been unwell for some years. Won't go into details as I think she might well be a MNetter however she has chronic pain and is understandably also suffering from depression.
Her husband works shifts. when he is on the early shift, she gets up at about 4 am to help him make his sandwiches and spend time with him. This has been going on for some months now. Her DCs are poor sleepers, so on early days she is awake from 4am until midnight. day after day.
She has told me that she doesn't have to do this, she wants to, but I really want to say more, and indeed tackle her husband, who I get on ok with generally. I have just seen her health get worse and worse and her state of mind get more and more desperate over the past few months and frankly if she could have a few hours sleep more a night, then I'm sure things would at least not get worse.
Sorry, this is a bit of a ramble. I'd really value some advice though, I feel I am letting her down as a friend by standing by.
