Welshwife thanks for input. I know all my figures, and the GP has known about it for years, since 2008 which they ignored., it only came up when my sodium dropped down to 126 two years ago,and then they panicked and took me off anti depressants which I had been on for 8 years virtually overnight and for the last two years they have just left me in a dreadful state of anxiety and depression, and I am afraid counselling does not work for me. My sodium went up and now it's down again , it's 130 at the moment, only found out cos I nagged for a test! And yes , I could change GPs but unfortunately they are all awful in this area, and believe me, it isn't just me who thinks that.
