I know that its easy for me to write and tell you to stay strong but I can also empathise turmoil of emotions you would be going through.
These are very uncertain times and worrying of uncertainty definitely increases anxiety. Like today things are fine for me and family but what if tomorrow similar situation comes up.
The silver lining is to stay connected to our soul/self/inner conscience. Being grateful and pray for others well being.
Also Dont worry about exam, its not above life. With right attitude lets face tests which life is giving. Stay spirited.
