My life is one big stinky S**t!! >.>?

I rly don't know what to do anymore.. I am 15, i have a broter who is 18. I live with my mother and father.. They are fighting over money EVERY single day since like 10 years!! I can't bear it anymore! My father pledged out apartment like 3 yrs ago since we had no money for the bills & food.. And now he can't pay the debt! He owns a lots of ppl money, his so called "friends" threaten him to return the money or it will end bad.. He even took a lot of money from my mother's boss since when my mom started working her boss was so friendly and stuff.. But now the boss needs the money back (he has a family to look after too) But my father cannot pay him back! My mom can't even look her boss in the eyes!! She is working her a** out, staying on work hungry half day 6 days a week and she is working for no money (thats the way she pays back her boss.. Well ofc he (the boss) gives us some money but they can only do good for food for like a week or even less.. My father got cut out of work and now all he does is staying infront of the TV whole day! We can't even pay the bills.. We have a HUUGE bill for the electricity and they cut us out.. But my dad asked for electr. from a neighbour so we have now.. We can barely get money for food, we have nth to eat but bread (literally) !! My brother is graduating this year and they don't even have money for costume for his prom, and for university.. All my fr's have these green cards or smth which family makes when they have a child to save up money for college/uni But Nooooooooooo, only WE Don't have this stuff.. I feel like my and mu bro's future is ruined! My dream is to go in the University of Tokyo once i graduate so i am working my a** out studying but even if I have the skills to enter i don't have the money! I rly don't know what to do! T___T My father now wants to go to another city to "work and send us money" since he can't find work at put city.. But my mom knows once he goes there he won't send us money at all.. He'll just leave us to pay his debts!!!!!! And my mom is sick, she has a weak heart and I am afraid that if smth happenes to her We will be left all alone!! Since my dad NEVER acted like he cared for out family! He always ignores us, when we say smth he goes like "Shut THE F**K UP, I AM WATCHING THE NEWS" or smth! I hate him so much!!!! My mom even wants to divorce but ofc she needs money for that so its impossible.. Even my mom's friends and her mom sent us money lots of times to have smth to eat but my dad takes like 1/3 of them to "work with" But he never ends up giving them back.. he even cheated on my mom few months ago and told a friend family about it (of they told us too) and my mother wanted to kick him out but she could'nt since all the debts would have become ours.. I rly dk what to do!!!!!! I feel like my life is ruined.. I have no chance for being happy.. Every night i lock myself in my room and cry, wanting to never wake up tomorrow.. Wanting to end it right here.. but my friends and my dreams r keeping me away from doing such a thing!! i have the faith that someday things will workout but every day we are getting closer to the bottom so i believe nothing can become better now! Please tell me what to do! Give me some advice!! I can't go on!!!! T.T
