Any advice or support welcome...

I'm 46, had a massive bleed 2 weeks after period and put down to peri menopause. Had missed a couple of periods for the previous months then 2 period 2 weeks apart. Went drs to discuss HRT and exam found lumps on left ovary which were confirmed with ultrasound as 16cm complex cyst. Ca125 was 65 and dr warned of ovarian cancer. 
referred to gynaecology and reassured as pre menopause risk is low with RMI of 65 (200+ is high risk).

MRI completed and risk increased to RMI 195 (intermediate risk). Referred to MDT who have advised surgery to remove both ovaries tubes hysterectomy also omentum and peritoneum. Surgery should be in next 2 weeks. 
The wait is horrendous.
Feel pregnant with the pressure on left ovary and unable to simply roll over in bed without sitting up. getting sharp pains in under arms/breasts/pelvic region- is this normal?? Or psychological?

has anyone else had similar and good outcomes? Or just want to talk?
