Yeah I was convinced I was dying, I went to the hospital at first because I thought I was having a heart attack. All they said to me from the blood test was that it showed I was fighting a virus, but I don't know how they would have gone about working out which one, they just told me to get some rest. I basically slept for the 4 weeks, lost a load of weight because I had zero appetite, was a crazy time.
Afterwards I kept going back about the heart palpitations and they did all sorts of tests and scans but kept basically telling me the same, destress, eat better, get more sleep, etc. When I told them I was tired all the time they told me everyone feels like that. But now it's cleared I can tell there was definitely something abnormal going on.
