Abusive father

Hello sir, I am a teen girl(14 years old). My father is mentally abusing me and my whole family which includes my 20 years old sister and my mother. He always argue on even small topics like if we don't want eat non veg, he force us on eating that and if we won't agree, he argues. My mother's mental and physical health is also depleting. We don't have any type of financial support other than our father's. However, he always threats us that he won't be supporting us financially if we don't listen to him. My sister is currently in college second year, still she's doing internship so that we could be helped a little that too only for ₹5000. Recently, we filed a case on him for mentally abusing me, my sister and physically too with my mother. But the police can't take this too long or can take any action on him. Moreover, saying that this case can only be handled by the court. But we need our security at least. He's been giving us threats that he would not be supporting us financially and will beat us if we try to harm him in any way. Please try to help us by giving any opinion on this. Thank you.
