I am facing abuse from my father.i want to leave him.

My father is emotionally abusive and I am on the brink of killing myself. Even though I told him of my suicidal thoughts he said to stop the negative thought and start thinking positive. At first I thought it was denial but even though I said this a lot many times he has continued gaslighting me. He has called me names, beaten me till I fell semi conscious and then poured water on me. I also got lot of seizures due to my depression.for that he stopped talking to me for 2 years. Surprisingly my seizures did get well. Still he used to call up his relatives and even my mom's relatives to tell them how my mother manipulated me because of which we r are not speaking. He would always bad mouth me, my mom and my sister and even though our family's income is more than 25lac in papers my father has never spent on his children and made my mom pay for all the education.
