"Concerned about operation"

I must say that having been recently diagnosed with breast cancer and having experienced a few visits to Southmead Hospital and also now having read some reviews I am feeling very anxious about being admitted for my operation next month. It seems that if it is not one thing then it is another thing wrong . When I arrived early for my diagnosis I enquired at the help desk for the restaurant and was told that there was a small Area right at the far end of the building. Here a few elderly ladies sold a few sandwiches and hot drinks - no healthy meals etc. I have been kept waiting over an hour and a quarter on both occasions for my appointments with no explanation offered re the delay . The information sent out to me states that my well being is of the greatest concern but I am not seeing much evidence of this so far . Maybe my expectations are too high ?
