It was thought (by my GP) that I had Covid at the very start, before lockdown & before testing based on the symptoms I had was in place.
I was so sick - in a way I've never been - for about 4 days. This included loss of taste / smell & awful vomiting. Neither were Covid symptoms at the time, so it was only later my GP rang back to say, 'it probably was Covid'. It's only in retrospect I realise how tired I was after, and for how long. I had difficulty breathing but somehow didn't connect it. It was such a crazy time with lockdown that I didn't think about it till much later.
I have Covid at present. Nothing like then, but also not mild. I'm on day 3 & feeling very wiped out, breathless, and then typical cold symptoms. It's not as severe as a flu but I definitely am sicker than I expected.
I am in my 40s, very fit, and otherwise healthy.
Oh, I was never afraid of getting it & also am sure I'll be fine again in a few days. I only didn't want to get it due to the isolation rules, as I'm a single parent & no real back up.
