Needing advice

How do you deal with a toxic family member? My Aunty who lives with my ma has lost it, and I don’t mean that in a disrespectful way, she knows and admits herself that her mental state it not that of a person capable of taking care of someone else.

She won’t let me see her and every time we try to talk she becomes aggressive and yells and screams. There has been a family argument going on for years and we cut ties for a while but still visited my grandma. A couple years ago when my ma was in hospital we would visit her and my Aunty would act rude towards us so I felt uncomfortable visiting her at home and my ma knew this. I then found out she was unwell and went to see her and she got aggressive and yelled at my sister and I (were quite young, 21 and 16)

Now recently my dad had gone as he wasn’t seeing her either and she said that she doesn’t want my sister and I around or seeing her.

How do i deal with this as it’s broken me.
