Those who didn't get it from a virus, where did you get it from?
Very curious about that.
My story: I was diagnosed 1,5 years after my first symptoms, making it impossible to identify the source. But: It started at a festival. The last day. Very hot and humid. I was sitting in the shadows, and I felt as if I'm being cooked alive. I went to the showers and tried to cool me down with cold water. The sudden cold was a shock to my system and I felt my heart beating out of my chest. The rest of the day, I chilled and partied again in the evening.
And the next day, I was weirdly exhausted, and my heart was beating unusually fast. Later that day I thought I had a heart attack. For weeks I was too exhausted to do anything physical, the doctors didnt help at all, and (miraculously in hindsight) I recovered over three months. I could live mostly normally, until I deteriorated again this year to the point of being bedridden and finally getting a diagnosis.
Of course it still could have been a virus, but other than my heart I didn't feel sick. Just weird. So, how about you?
