I don't know why they sting. It is pure evil. When you take something that they don't like they will bite the tar out of you, too. I had one sting the back of my eye one time. I decided I'd rather go blind than let those mfers feed on me and make me miserable, so I took another dose. These things are intelligent and evil. They LOVE sugar, chocolate, caffeine, milk, and they will make you crave it.
Brace yourself for a battle. I think it is a spiritual battle. Because I am so irritable and prone to anger for no reason when they are on the run. They have the ability to change people's personality and make them mean. That is why the world is in the condition it is in. People are infected and don't even know it. Parasites are fighting the wars. It is sickness. Literally.
They just told me they are not defeated.
I am praying for you some more.
