Josie, I honestly could have written your post myself.
My lovely Mum died in February after battling Mixed Dementia for over 6 years. Her funeral was in March. My 90 year old Dad (who suffers from Vascular Parkinsonism) and I delivered the tributes. Somehow we managed to hold it together.
Everyone at the funeral was saying how my brother and I were so marvellous and couldn't have done any more and I felt such a fraud. So many times in the last few months particularly when she had deteriorated so badly I had felt so resentful of our situation and I wished it could all be over for all our sakes. Yes I could have done more, I could have spent more time looking through the photo album with her (the only thing she enjoyed towards the end), or made more cakes for her and Dad, or taken her to a garden centre to give Dad some space. In the days between the death and the funeral I wished I had been a better nurse to her, I wished I hadn't got cross, I wished I had been more patient, I wished I was just a better person.
And I was so bitter about what we'd all had to go through. That my lovely Mum had been taken away from us, piece by piece, leaving a frightened, sometimes violent shell who lost the ability to speak, refused to wash, wasn't able to dress herself and was doubly incontinent. The person she was would have been so mortified by what she became.
And yes, my brother and I talked about how we were fearful that the wonderful memories of our idyllic childhood would be taken over by the experiences and feelings of the last few years.
I am so happy to say that those fears were unfounded. Now that she has gone I remember the happy times, daft things she came out with, funny events that still make me laugh and just what a wonderful Mum she was. Writing my tribute for the funeral helped with that and also going through her things, finding cards we'd made as kids that she had kept in her divan drawers for 40 years, her hair curlers, her crochet hooks and little knick-knacks that just were HER. Yes I cry when I think of the lovely times we had but they are, I think, good tears. The misery and horrible things that went with advanced dementia will never leave me completely, but they were not my Mum, they were something separate.
I still acknowledge, in my heart of hearts, that I could have done more but it would have been at the cost of the few shreds of my life I had left to me. At the end Mum had a fall which set off a chain of events including infection and, we think, pneumonia. The GP said we had to look at End Of Life Care and just 5 days later she had gone. The local hospice were amazing and sent carers round twice a day to do Personal Care, which was such a relief, especially as we didn't have a Profile Bed. We all got the chance to say goodbye but her final illness was not drawn out, thank goodness. She was at home right up until the end and that IS something I am proud I managed to accomplish.
She died at 2am. I was laying beside her holding her hand. Bert the cat was curled up at the foot of the bed. Her breathing had changed so I knew it was close, so I told her Bert and I were there and she wasn't alone. I told her I loved her and was very proud to be her daughter. I promised her I would look after my Dad and my brother so she didn't have to worry. And then she took her last breath, like she had just been waiting to hear that so she could go.
The time between the death and the funeral is a sort of state of limbo. Since then I have managed to let go of the feelings of guilt and fear that I hadn't been the saint everyone seems to think I was, because I am not a nurse by profession, I didn't have a shift that only lasted a finite period of time and then go home to my 'normal' life, I was on duty 24/7 and I am human and imperfect and sometimes get cross or act in a thoughtless way or say things I regret when I am exhausted and distraught knowing I am losing the person I love most in the world.
Now I find myself talking to Mum in my head. Sometimes I'm in the car mulling over a problem, sometimes I'm watching a TV programme that she might have liked, sometimes I'm making a cake and asking her advice about how much baking powder to add if half the flour I used was plain by mistake... I didn't do that when she was ill because she was still 'here', even though she wasn't. Someone at the funeral said 'At least you can grieve now' but in a way I did my grieving while she was still alive, because I'd lost my Mum a long time ago. Now I am free to miss her, and part of the missing her is having the happy memories come back, tears and smiles and all.
I honestly believe they will for you, too.
