I need help figuring out family problems?

what would you do if your dad has never really been there for you, you always feel down because you have so much family stuff going on like almost loosing your house, not knowing where you going to move to? stuff like that. i'm going through it all right now and i don't no how to handle it. my family is steadily breaking apart and since I'm 14 i can't fix it. i have school and sports to worry about not worrying about my house mortgage payemts. didn't get me wrong whenever i have the extra money i ask if my mom wants it, I'm definitely not selfish, but me and my sister are getting depressed and all my moms strength is falling apart, shes such a hard worker and doesn't deserve any of this. i need some motivation.
