I just can't tolerate my life anymore

I live in a family of 4 members. It would be a lie if I say we are normal. I am 16 right now my parents been fighting since I was a baby even before. My father drinks a lot which my mom can't tolerate so she fights him. It wasn't that bad until some years recently. My parents have become completely toxic. I am an artists, and currently not independent. Not only my parents use some of the most severe language you can think of, but also there is some severe violence included. My father makes some of the worst remarks to my mother. That's the least of the problems, there's been a lot of times that if me and my sister wasn't there, they could've killed or harmed each other severely. My mental health is tearing apart. I don't know how I would be able to focus on my career with every night and day happening the same nightmare again and again. It had reached to a certain extent that I considered taking my life. I know this sounds not so bad but it's freaking difficult right here.
