am i an aminal

i was eating some bread like right before i made a peanut butter sandwich and i saw my finger and was like "okay lets not bite my finger". and within that same second my body literally jerked itself forward, i chomped on my finger like a cartoon as hard as possible and it FUCKING HURT. ITS RED. WHY DID I BITE MYSELF?????? RIGHT WITH THE CANINES TOO. like, i felt feral. because i watched as my body DELIBERATELY FORCED MY HEAD TO MY FINGER AND BIT IT *AS I WAS PULLING AWAY* 

disgusting
