@resurrection26,
I am a nurse. I am not a doctor.
I think that you are probably going to be OK.
But I can't really be sure with only knowing what you can tell me.
Breathing in milk, can sometimes cause an infection in the lungs.
If you have trouble breathing, then you have to go to the doctor or hospital.
From what I understand you just sort of feel yucky and have a headache.
Is that right?
Drink lots of water. Eat your vegetables (or at least eat what you can).
Have your parents check back here if they have any questions.
This talk should really be with your parents.
I should be talking with them.
If it is hard to breath, then you need to tell your parents.
If it is hard to breath, then they should take you to the doctor or to the hospital.
