What Covid-19 has done to me

It takes you awhile to know you got it.
It's known Nationwide but stays silent.
The world's most violent murderer, yet millions have caught it. 
Who is this beast that has taken over my mind? 
Mentally I'm breaking but on the outside I feel and look fine. 
Who would have thought that staying home was once a dream come true.
Now it's making me lose my mind, I only see half your face over my mask.
I'm paranoid over every sneeze, a cough makes me want to back up more than 6 feet. 
Covid-19 what have you done to me??
