I feel for your cousin. Have you or other family members reached out to her?

I think my own mother would be exactly like that with me if given half the chance but she still has my very tolerant and patient father. She is a controlling and narcissistic woman who verbally abuses him and makes fun of him all the time. He cannot speak or give an opinion without her making sarcastic or condescending comment. She thinks she has superior intelligence even though dad is a professional with very high level qualifications and experience. Both my siblings left as soon as they could and moved to the opposite side of the world to have limited contact with her and I have stayed local only because I had a family and wanted to stay close to my father. I feel for my father but its too late to get him away from her. On the flip side I fear the day he passes away as she will definitely turn her attention to me. His co-dependency is the only thing standing between me and her.
