Sorry, this has undoubtedly been done.
I had Delta in early December which absolutely flattened me - would have been bearable if not for the anxiety, racing thoughts and insomnia. It was grim.
I've just got back from a weekend in London, lots of crowds, tubes, busus etc. Started sneezing and feeling a bit feverish today, and similar anxiety feelings 😐 wouldn't be the worst thing in the world if I did have it now as we have a holiday booked in August. Just wondering how bad it would be.
