Radical hysterectomy - please help

Hello, 

I am 44 and due to have a radical hysterectomy tomorrow, I am absolutely petrified!

I had a tumour removed from my cervix 1b3 which showed clear cell cancer. 
Ct and mri were both good with no sign of spread.

I am absolutely petrified and also petrified they will find something else even though scans were clear. 
 

They are also taking my ovaries which puts me into surgical menopause but I am thinking nothing can be worse than what I am already going through x
