What do to control my feelings?

um well me and my family all had a big argument because i said that they never have time for us . witch they dont they always put the work before us and its 3 of us. My mom also never wants to make us breakfest . she said that shes busy cleaning thats her "work" so i told her this morning. its always your work im tired of us suffering you guys never pay attention to us you cant even spend 1 minute with us at all. we used to be able to talk so much but now i can hardly ask her something cus she is always busy ? I am the only one that feels that way apperantly? because my other 2 sisters yelled at me saying i dont do my chores . and she said if i would help out maybe they would have time for us? i honestly dont think im being selfish . i mean what parents dont spend time with their kids . ? we can clean the house later? but they always care about the money the money is always before us. Help . am i being selfish ? or what should i do this is the 3 time we fight of the same thing . Help?? !!
