What do you think is she family?

Just to be clear I am a girl and no I do not want to sleep with this girl I am sick of people telling me to help her b/c she is my cousin (she has a horrible addiction to meth and has spit on me and fought me when I tried to talk to her) She is my half aunt’s half great niece. Me and the half great niece have no blood between us but like I stated above we have my half aunt and her half great aunt in common are we blood related and if so by how many degrees? TIA
