How concerned should I be that my poops have more blood than stool?

no, hemorrhoids would not cause that amount of blood.

Every time I cut myself, I'm making my veins stronger.

Very concerned

I'm hopping OP is exaggerating and not actually pissing blood.
Otherwise he has a major problem.

But since he's American, he's probably gonna die

I'm going to guess that I have a tear in my rectum (how serious that tear is, though, is debatable). Is there anything ai can do without going to the doctor?

I'd be worried I could think of no reason to why a rectal tear would happen.

Are you gay and/or take shit up your ass?

That's kind of a personal question...

Nice bulking OP I've just pooped blood once when I ate around 7000kcals in a day.
