Actually, on the subject of guilt, I have just literally this minute had a kind of epiphany, which I will try to explain... sorry might be a bit long and rambling.
I was the 'daughter round the corner' for mum for 20 years - increasingly more so over the last 10 as her health declined. I did the day to day grind, admin, shopping, taking to appointments, liaison with whoever etc. Visited at least 5 days out of 7 and then more often as she got worse, accompanied by the DDs as and when they were around, all while running my own life/work/home. Dealt with all the medical emergencies, the calling the ambulances, the hospital admissions etc.
DB and SIL got to ride in like the famous white knights for 3-4 days here and then, taking mum out for little lunches, to the garden centre, planting her pots for her, doing manly things like changing light bulbs. So they were the perceived heroes - because they were fresh and interesting, and because when they visited they didn't have real life to deal with.
Yet DB feels terrible guilt about the way my mother died (on previous threads) and lays enormous blame on me for not being caring enough, for not accepting his status quo - she's lovely, she'll be fine. To the point where we had a terrible argument (instigated by SIL actually) and our relationship I dont think will ever be the same again.
Despite the fact that he was the white knight, I can remember, about 5 years ago, him being absolutely vicious to our mum, to the point where I had to physically stand in between the two of them - she was 83ish then and very frail; I am 5'4", he is 5'11", and I had to literally get in between them because of his verbal abuse and standing over her while she cowered in her chair.
But I have just realised: that's all about HIS guilt, not my guilt. I did every bloody thing I could for 10 years, it might not have matched his expectations, but that doesn't matter when you are not the person on the ground doing the daily grind. I have no guilt to bear for what happened to mum - it was truly awful, but I did the best I could at every stage. And I should be proud of what I did, and actually, I am.
Sorry, that was a bit of a rant!
