Thanks for writing in.
Craving blood and eating raw meat is definitely not ok and you could be seriously ill soon. There are a variety of parasites transmitted in this way including neurocysticercosis
which can cause seizures and form a mass in your brain.The yellow colour in the eyes can be due to the excessive blood/raw meat you're taking and it is due to a lot of bilirubin
( which is formed due to breakdown of heme in the blood and meat)
Please see a psychiatrist
as soon as possible. This can get you into a lot of trouble,
