My sister has put a knife on my mother for not being able to get married

In my country we don’t have separate places to live like an apartment or so. We inly have hostels for universities and some local ones which are to be honest extremely haram to live there. I did talked to my parents to atleast send her to another university where she has to live in a hostel but she just don’t move and I don’t have a good intellect to get into another university I have extreme exam phobia with multiple anxieties that have numbed my brain into understanding anything normal. It was extremely hard for me to pass a very easy piece of cake kind of an entry test or else I would have moved away. But would that have secured my parent’s well being?
