Hey CheerBear,
I just had my proctectomy on Dec 18, so it's been 4 weeks. For me, the worrying and anxiety prior to the surgery was the worst part. Once the surgery is complete, I woke up with nothing to worry about. It's suddenly all about recovery and you become focussed on that.
I'm not dismissing your concern. Your worrying is certainly with good reason. The surgery hurts, the recovery is long, and there are risks.
You say you work in a shop, so I assume you are concerned with lifting, and mobility and such. For me, I found my abdominal incision much easier to deal with this time than when I had my initial illestomy surgery. The strength in my stomach muscles returned much quicker and moderate lifting is fine now (I have a playful 2 year old daughter). Mobility is only ok, and it's awkward to get in and out of a vehicle. I work in an office setting, and I find the long periods of sitting to be more painful than walking or lifting.
Good luck with the surgery, and the anxiety. I am being entirely truthful when I write that the worying was much worse than the recovery has been. I remember my sleepless nights, and the fear. That is all gone now, and I am actually enjoying the challenge of recovery. You will feel that way too.
