I agree with what the others have said. I was diagnosed at the end of August, same surgery as you at the end of October and it was the idea of surgery and the recovery from that worried me as I’ve never been ill before but I trusted the team who did a top job and didn’t think any further than that. I am now facing chemotherapy as a belt and braces treatment and am not thinking beyond that.
It can all feel very surreal (it does to me) as though the real me is just a bystander, think you have a very healthy attitude so just put one foot in front of the other
