I can understand how bad it would be for you to get stuck, away from your family. This Covid is anyways so depressing due to the lockdown and restrictions (which are in a way madatory). With family, it is still manageable because you have someone to talk to and share your feelings and laugh with. But away from family that too so far in this atmosphere where you don't know what will happen when. Great that you are able to come back. Please be safe and have a nice travel.
I am also very scared of PCR tests. The first time I took it was when I was in labour, apparently, it was mandatory before the doctors could operate on me. I hated it. Labour and on top of it someone putting a stick inside my nose. And I remember they did put another stick in my throat as well to take the swab. It was awful.
I recently got another one because I had to travel and it was mandatory to get a negative test to visit any other state. It was equally irritating this time too.
