What is the legitimate position of a girl who lives with her brothers who earn money from selling drugs, knowing the impermissibility of living alone?

The sister is advised to counsel her brothers and explain the prohibition of earning money from drugs. If all their wealth is illicit, it is not permissible to benefit from it except in cases of necessity or extreme need (if lawful means are unavailable). However, if their wealth is mixed with illicit gains, it is disliked to partake of it unless there is a necessity or need. It is not permissible for her to separate from them and live alone, fearing that greater harms might result.
