I hate my mother. she is a monster to me

I had a fight with my mother a few moments ago(I am writing this post in all tears). The reason is that I have been asking her for my shorts for about a month now, but despite all my efforts she refused to give it to me. She says that all my shorts are torn which is NOT possible because I only wore them for one summer and I saw her putting the summer clothes in a box, so it is not possible for them to be torn.

So, I took the matters in my hand and began searching for them in my home and in the process I disturbed some of the positioning of the previous clothes, and as I was in anger I refused to correct them when she asked me to do so. Then our fight went on to be violent and she hit me with leather belt. I said some unpleasant to her based on my experience described below(you will get why I said certain things to her). I said that she is a bad women because she has no public manners and whatsoever. She continued to hit me with belt and asked to hit her back(she is a psychopath). She continued and I was so frustrated that I kicked her in stomach(I don't regret it).

That is the reason why we fought today. Why I hate her is because whenever we fight (like today) she would call her parents and our other relatives and tell them the part in which I am a villain and she is a hero. Even now she is probably talking to her mother complaining about me.
I have been asking her to give me my shorts for a MONTH now, how can I be a villain. And its not just me, whenever my father and she had a fight she would threaten my father to give him divorce if he had not agreed to her terms.
She always get what she wants by threatening him. And whenever my father or I wanted something she would again threaten my father of divorce and beat me, and my father and me being "SANE" we would end up compromising to her.
Me and My father have no one with whom we can discuss these type of matters so we just buckle up and let it go.We are not like her, dragging other people in our personal family matter is one thing we can't do, she is a psychopath and have no regards whether or not someone is interested in her story.
But over the years she had already done these things to my father and now he don't visit my mother's parent and why would he they have no respect for him, thanks to my mother.

She has no public manners. For example, she has some genital skin problem and she would itch them in public place, in front of other people, in front of her elders, her parents, in front of me and my 14 year old brother. She is not even ashamed of doing in front of public, we told her so many times to treat her parts properly but she would again end of threatening me and my father.
Of all of her clothes she would wear those which is most torn up and go out wearing those. My father and I objected it many times but she would end up fighting us rather than correcting herself. My father gave up eventually as one would assume him to because my mother is impossible and she cannot be talked to sense. What could be the possible reason behind wearing torn clothes unless you want to show your body.
You cannot talk sense to her, she won't admit that she is wrong (NEVER), she would fight you to hell rather than admitting her mistake

We went to visit our relatives some time ago and she bought sweets worth Rs.1400 ($21.33) and when me and my father questioned she again had her battle form up and ready.

She has a lots of diseases and my father has spent half of his income in treating them all of the doctors she had seen over the time have strictly advised her to change her lifestyle and maintain a healthy body and diet, but she never took it seriously and continued to go on with the lifestyle she has been living that got her in this state in the first place.
She just wastes my father's money and gave all of us problems.

I don't know what to do, so I just end up ignoring her and not saying a word unless I had no other choice. I need help surviving with her.
Things that I am experiencing have already been experienced by my father. I now know, what it feels like to be in place of my father.
I hope my other to die. I really hate her really bad. I pray to god that she die early.
