Help! How can I control my extreme anger outbursts?

Hey everyone, I came here to find a solution for my severe anger outburst. It is going to be a VERY lengthy one so please be with me. My parents are good people and like every other parent they have always wanted good for me. But whenever there is some problem, they tend to make personal attacks on me, especially things that make me severely insecure. So recently, I have lost my job. My parents impliedly misbehaved with me even before this. This is because I chose a course of my own choice, I selected a boy who has been with me through all my thick and thin and who respects my parents even more than his own family, still they question my choice just because the boy I selected is of dark skin and short in height. Losing my job was the last nail in the coffin. My parents have been misbehaving with me ever since then. I still did not say a word to them. They have their wedding anniversary today. While on our way back to home, I was upset because my sister had lost my ear phones the very day we started our journey to this trip. These earphones are expensive and were gifted to me by my boyfriend. My sister kept it casually and lost them. I still did not get angry about it and calmly stayed with my family throughout the trip. When we were getting in the car this morning, , my parents still showed no concern towards my problem and when I calmly tried to explain why it bothers me so much, they out of nowhere told me that "you lost your job because you're so non cooperative". I was appalled at their response. This really upset me and made me severely mad at them but still I had not more than app slight argument with them. Now when they stopped the car on the way to grab some morning tea, then also my mother said "Nobody liked you at your workolace and look at me everybody likes me at mine" . Not minding much, I started looking for my earphones and found it in some random corner of my seat. My family said many things after that but I kept mum. But I lost it after sometime and told them about how they never accept their mistake but it's always a problem when I do it. Just few days ago my sister misplaced my mother's earphones too and my mother ACTUALLY started crying sitting inside the restaurant but when she found her own earphones back, she casually said not more than a few lines to my sister and when I did it , it became an issue for them. The problem now begins. I could not take those personal attacks anymore. To be honest , my mother's marriage has not been happy. She has cried each day and has been upset on my father many times. I told them "why do you even want to celebrate your marriage when you have not been happy at all?' This is because she has been attacking my insecurities since morning and I could not take it. After that my mum burst out in anger and said such shameful things about me and my boyfriend. She literally started to abuse him. Now I was holding tea in my hand. Somehow my hand shook in anger and half the tea was spilled on my legs. In a fit of anger, I poured the remaining tea on my mother's side of the seat and also the tea cup. My family went nuts after this and even I was shocked to the core about what I did. So I seriously need your help or at least guide me in how I can overcome my anger issues because I seriously want to get out of it. I am tired of taking bad karma on my head. I really want to change.
