I had a really bad SV when I was 7, for which I ended up in hospital with a drip in my arm. The V and D lasted for a week, it was unbearable. After this, during my recovery, I developed severe bouts of N that nobody could diagnose and i had to go in for all these tests. Turned out it was anxiety N. It went away when I was 12 or 13, but has come back recently after my mum got a SV and I got so worried about catching it - this was just the first trigger that set off a downwards spiral. The other half of it was that I worked at a cancer hospital for a while and seeing people in there gave me the worst health anxiety. I went to work every day feeling N for 6 whole months. I had to eventually quit the job and it's been with me ever since. It's more mild now and I don't get N as often, but whenever something triggers it..... I just wish I could go back to that beautiful window between age 13 and 22 where I was fine and had no fear
