Terrified ! Hysterectomy soon

Hi everyone dont even know why i think posting on here will help i guess im just looking for a friendly ear !  After attending every smear since i was young I'm now 55 and 3 years ago had borderline changes. Routine smear in April severe dyskariosis . After Loop treatment was recalled six months later with high grade dyskariosis ? Invasive squamous carcinoma? So after an attempt at another loop consultant couldn't get to the cervix as it was too short and would probably need a cone biopsy under General anaesthetic.  I suffer from chronic anxiety and panic attacks and couldn't face another 6 months of what ifs so she agreed to hysterectomy . I'm so terrified. Can't sleep . Crying all the time I'm now terrified of the operation.  When will it all end ? 

Sorry for babbling on I think I just need to hear I'm not the only one
