I don’t know what is wrong with me.

I crave the taste of human flesh so badly, when I don’t eat especially. I look at people like their food and when I realise it I try not to, but it’s so hard not to. I crave to bludgeon someone at the back of their head, skin them and cook them. I know it’s disgusting of me but I can’t help these urges and thoughts, I’m currently 17 (18 in a few days) and i have over the years started looking at friends and family as food. I don’t want to hurt anyone at all and scared to tell a professional in case they take me away from my baby (my cat, she’s such a sweetheart).
