So sorry. I'm right with you. I also lost my mum on the same day and within similar timescales.

We knew shortly after the New Year that her cancer had spread - but we thought we had time. Sadly mum spent her last weeks on hospital. On the plus side she had excellent, around the clock care - and we were able to spend as much time with her as we wanted. 
Unfortunately we have a wait over three weeks for her funeral. Just as we are coming to terms with it all - a delayed funeral will be like picking a scab off the wound.

We are fortunate that we have a strong faith - which has been an enormous source of comfort. All the same, there are good days and bad days. Little steps, I guess...
