Can somebody please help me i can't take the pain anymore i'm only 14 and i can't do anything?

see about a year ago my sister was deployed to kuwait and well she got kia killed in action and since then my parents have been going insane and i had to bottle the pain so i can help them get back on there feet little that i know that my father was not doing well and he started drinking until he finally lost his job. everything was going alright except my mom didn't recive any benifiets because my sister got married 2 months before she got deployed and she didn't get the wedding she wanted her inlaws wanted a nice cheap crappy wedding even though my parents were going to pay for everything. any ways all the money went to her husband who hasn't even put a tombstone on her grave instead he bought a house with that money. well christmas 08 my dad got worst because that was my sisters favorite holiday and he started drinking i asked him if he can please stop since he already had his license revoked and had a crime of dui's i know thats bad but during january i came home from school and he was wasted on the couch and i couldn't handle it any more i went insane i yelled at him and told him he wasn't a real dad that i hated him and that he only loved his daughter he got mad and left because i kicked him out of the house. next thing you know he is arrested and since everyone else was a citizen except for my dad immigration wants to deport him back to mexico and i don't think its fair to take away my dad and tear my family apart the country took my sister who was like a second mother to me and now my dad which is even worst we are losing our house also and my mom is trying to save the house and my dad and she can't handle a lot of stress i feel mostly responsible for this because i feel that its my fault that my dad is going through all this and also my mom. i am asking for anyone's help to try to talk to some politicians and that are nice enough to help me and help my dad stay with us. even if i have to go beg to the president of the untied states president obama i will just please help me get in contact with higher power please i can't deal with this no more
