Help/support

Hi,
I was hoping that someone may be able to guide me with the following query please?
My husband was diagnosed with cholangiocarcinoma last January. He was admitted to hospital literally with no warning signs and spent the best part of 8 months in hospital between chemo, surgery & complications. I was pregnant at the time & had our fourth child in the middle of it all. I have four children now, 7,5,3 &1. We all did our best to get through it at the time and things seemed to be going well.
Three months ago, my husband got sick, again very suddenly, and was admitted to hospital due to complications from surgery and he was an inpatient for the last three
Months. This time around it has been a lot harder on us all as the kids are older etc.
I feel like we all need some help adjusting to our new lives, in particular the kids as the suddenness & uncertainty of our future seems to be having effects on us all.
Where do I go for help for us? What options are available for children of their ages?

Many thanks for any replies.
