I throw up a lot
That's very concerning. Do you throw up when you eat something?
Yes, ALL THE TIME. It is annoying, but I refuse to go to the doctor about it.
Throwing up constantly is a sign of a more serious physical issue. It would be helpful for you to make an appointment with the doctor so you can receive some help.
Are you a doctor? Where did you learn this stuff? I don't see it being a disease at all.
It may not be a disease but it may be a physical illness that you still need to get treated for. It may be something dangerous and you may not know that you are in the brink of dying, so I do suggest that you get it treated right away.
