The hunger for blood

Another day in my life , i know there's something strange about me .
But i don't know what... Whenever i see and smell blood i have the urge to taste it.
That shiny red fluid mm... Once i cut my self by accident and my head startted to spin.
My hands were shaking and my stomach was begging to drink . As i always did i licked my blood away.
Then the strangest part , as i licked my blood my heart started to pound .
Like there was a race going on inside me ! I wanted more . It tasted so good !
The wound stopped bleeding and i lost consious ?! Since that day i need blood ! I don't know why but food doesn't stop my hunger .
Yes, i've been thru a lot . I'm 16 and i live alone something killed my parents but no one knows what but it wasn't a human .
Sometimes a have wicked dreams they look like memories , memories of my parents.
A demon look a like attacks them and then i wake up all sweated ... But i swear that i'll find out what this means .
Next week school starts i hope i don't have another hungerattack
