Someone save my life please?

I will do my best to make this short, I am 21 years young, university student, and an athele (runner) competed/competing in many marathons - I have great dreams to build great things for the poor and needy - I live with my parents at the moment (In Kuwait) I do not have a option to move as it is not feasible - my parents have been married for 29 years (NOT HAPPY 29 YEARS!) always figgthing day and night! I am tired of it! but i CANNOT see my mother suffer (My dad is mentally ill, he is taking over 10 medications EVERYDAY! - between years 2002-2007 my mother was a millionaire and had hotel in Virginia but due to my father we came down to having ZERO and owing people money and we left the states! and she has been running her own business for over 20 years and she is the breadwinner, my dad is always wasting her money! applying for immigration for the entire world and at the end gets rejected! he recently for the maybe 100th time applyed for london and paid and no answer, same for new zealand and this is a MAIN source of arguements in our damn house, physical argue, verbal so much bad language, emotionally everything! if my father did not exist it would be no fights! but he is not at fault, he is not normal! he takes pills and he has so many problems mentally but my mother's patience is done! she cannot afford her useless expenditure anymore and when she denies there is cuss words, argue, and more, just like today! I have been seeing this for so many years! I recently asked a question regarding the only way I see is to kill him? or report and get him taken to the mental hospital here? Is this right? MY mother doesn't agree with any of this! and she won't divorce either! she says he has no where to go but then she can't take it anymore and nor can I, he doesn't work, m ake money and thats ok but he is troubling us all and if he didnt then there is no issue! but this has been on for 20 years! and even today there was a big arguement I was close to taking a knife and doing something... I am really ready to serve few years in jail if this gives my mother peace! please help me, I feel so helpless....... i am just given up i dont know what to do! i feel like sooner or later i may do something...
