Can someone teach me how to sing when you're sick bc that would be a big help

(Part one)

I know the playing sucks but yeah this is a song I'm writing

WHY DO I KEEP DOING THESE IN BLACK AND WHITE WHO KNOWS

I CAN SING THAT HIGH?????

(Part two) once again voice is strange sorry

Oh lord my sick voice is rough

Literally wtf was that gay shit chill out

AGHHHmorgan lol

OKAY MY VOICE KEEPS SHAKING IN REALLY WEIRD PLACES WHEN IM SINGING RIGHT OKAY SO WHEN I SAY "STARE" IT DOES IT WHY SOMEONE PLEASE EXPLAIN

I like this chord progression
