Story My sister told me to go unalive myself and my mom acted like I was the problem

[Imhopeless]

Nothing more to add. When I told my family I need to do some tests to get my medications my younger sister told me the only real med for me will be death. When I smacked her across the head for that I got yelled at.
Went to my room and cried.
Later my mom wanted something from me but I refused to cooperate saying why should I help her when she doesn't care about what my sister told me and that who's fault it'll be when I actually do it and got even more scolding, she left.
Came here just a few minutes later asking me for something, again I didn't said anything because why should I when I don't matter, got called "a cunt", "vile" and something along these lines.
Now I feel like I was out of the line, taking it out on my mom even though she didn't really do anything.

The sad part is she wasn't wrong. It's the only way to escape this hell.
That being said, family drama is the reason I don't associates with most of my own.
In the end, whoever is right or wrong doesn't matter. Actions matter.
You don't have to get along with them, just show up if thats what you want.
