My mums 90 and has just suffered a massive nervous breakdown and now has sever depression and psychosis.
Due to this it is impossible to have a normal conversation with her. I live 800 miles away and so can't visit often.
Our relationship was always characterised by weekly phone calls making sure each other was OK and swapping news etc.
I so so miss that contact. I feel like she has died 
I have started writing to her to keep in contact, but it just isn't the same.
It came to a bit of a head today as my older sister bought herself a new car out of mums money. I don't have an issue with that as such, but I really want to talk to mum about it to check she agreed and I can't !
My sister said mum had agreed to it last year before Dad died, but such a lot has changed since then and I'm not sure she would say the same now.
She is in a home as she can't really cope on her own and so my sister looks after her finances.
I just really miss her. Its not just the car thing, it has just bought home how she is now absent in my life
