What's happening?

What is happening to me? Am I sick or somethin'?

Every morning wake up and I head to my bathroom straight up,
but then I coughed up spills of blood.
The same old thing happened to me since last Tuesday.
It's been a week now. I feel absolutely fine, but why there's blood comin' out from my mouth?

It's red in colour. It's blood, I'm telling 'ya.

For Christ's sake, I'm only 19. There's no freaking way that this is cancer.
I've told my parents about it but they don't seem much of a shocked reaction. And for that, I'm shocked myself @_@"
They'll take me to the professionals' help soon enough.

Oh my good Lord... what is going on?
