Janet...so very sorry for you and your family and also poor Mum too.
Janet when i went through it with my aunt, i had a little talk to myself, about how much her quality of life was not as it should be, my aunt was always a very fun, independant, and proud woman, and it really upset her over the last few years that her body was letting her down so much. She always used to say to me "in my head i can do what i want.....but my body is telling me different"
I know she would not have wanted to be here after her illness, which would have made her even more dependant, even though it was hard to see her go, i knew in my heart of hearts it was for the best for her.
You are a strong person Janet, and you will get through it too, as i have had to, it is very hard, i have to care for my Uncle who misses her so much and is just a little lost soul without her by his side. I try to always talk about her with him and we laugh now about what we know she would say in certain situations - but it is still hard.
I am thinking of you all....god bless
