I have anxiety and often worry about symptoms more than usual but today I woke up with a sore throat and have been totally exhausted, I have slept on and off all day, just feel totally drained. Don't have a cough, more like occasionally needing to clear my throat? Just feel generally unwell. Was going to order a home test kit just to be sure, but worried it's negative and then if I do actually end up with COVID 19 would I be able to order another test kit? Any help would be appreciated, thank you
