I'm reading many threads about people who have symptoms, or who are scared, and who want to call 111 "just in case".
I know this is going to run counter to everything you want to do, but, please, DO NOT CALL until you have thought this through rationally.
The instructions are clear, and specific: only call if you cannot manage the symptoms on your own (and one of the symptoms is not anxiety). In other words, call if you realise that you are becoming too ill to be at home.
If you are too ill to be at home, then 111 is going to be very important for you. To have it inundated with calls because people are having symptoms, but they can cope, or they are calling 'just to be on the safe side' while still being able to cope, is what is going to overrun the system and put those who really need care into critical danger.
That is all.
