I am looking for advice/ help

My Future father in law has recently been diagnosed with a brain tumour. It’s incurable and he has 2 years. This is all so fast and came on so suddenly

I have so many thoughts and feelings and trying to be so strong for my fiancé and his mum/ family It’s been so hard trying to wrap our heads around everything.

The point of this post is for some advice from strangers to get a different perspective

Our wedding is in less than three months and my hen do is next week the same week as his brain surgery- which is going to remove some of the tumour but not cure it.

With how we are all feeling. It’s been so hard on us all I want to cancel the hen do and the wedding Should I ?
