A sad party

In the evening, I had made an appointment with my friends to go shopping, but my aunt called me to let me go to the restaurant to eat, my aunt and my uncle got together every year after going to the grave, their old sisters got together, this time my mother was too busy in the day shift, there was no time to pass, my aunt let me replace my mother, originally dressed beautifully, crying during the meal can be miserable. You must be very why I am crying, let me first talk about my family situation. My family of 4 people, my mother is the pillar of the family, my father has been cooking at home for many years, he suffered from cerebral infarction the year before, and now he is a bit unresponsive, and his brother suffers from mental illness and beats people from time to time. During the meal, my relatives talked about my family situation, saying that after that my family would depend on me, my brother could not count on it, and he beat my mother. I couldn't help crying at that time, this is the elders have not yet found out, it is difficult to open the topic, I do not cry, a moment later came to my family this topic, said my family this disease family genetics, my grandmother, my 5 grandfathers they are a little bit, talking about me I cried again, and can't help it. My second uncle said that when encountering this kind of thing, people with ambition can handle it very well. I admit that I have no ambition, when I was very young, my brother suffered from mental illness, every day he beat people, he pressed my mother to the ground, smashed my car, pressed my father to the floor of the corridor, slapped my mother, all these years are like this, every time I am close to collapse, he eats very strong, we can't beat him, am I a failure to live?
