CPS.

I'm not sure if I have to state this, but I am a minor. This is a throwaway. My life, as of late, as been horrible. My half-sister (who no longer lives here) reached out, and asked if she should call CPS. Trigger warning for this, but my father and mother are abusive. I don't know if this is the right subreddit, but I really, really need this advice. Should I say yes?
