Okay guys so this ones kind of weird but

>been a poorfag whole life
>live with mother and grandmother in same apartment while going to college
>mother's a semi suicidal depressed wreck
>grandmothers a total cunt and shits all over her whenever she feels like it

basically, shit i've had to put up with for most of my life. Now the problem is that recently she has basically stopped showering for months on end. Which means she smells like shit and b.o. to the point where it's unbearable. Whenever my mother or I try to remind her to take a shower occasionlly she throws a hissyfit and starts screaming at us.

So basically, what do? How can I make her take a shower. How do I orchestrate somekind of intervention so the stubborn cunt will at least keep basic hygene.
