Constant vomit ER?

Anasteja
Can't keep anything down. Not saltines, Cheerios, smoothies, water, Gatorade, nothing. At this point I don't know what I'm throwing up. Because I can't eat. And at time I have seen drops of blood in my throw up. I don't know what to do. Should I go to the hospital? I haven't felt my bedroom in 2 days. Anyone else going through this?
