Confinement does have certain advantage.
Being forced to sit still for a good while gives one time to clear ones head, and do somewhat productive things like continue vocal lessons and remain focused.
I believe the worst of it is over, as I have not shook in some time now. And I woke up without painful and obvious signs of dehydration and exhaustion. One more night of sleep should be all I need.
Why am I under the impression that my miniature health crisis will inevitably hurt someones feelings? It always seems to.
