I am sorry you are going through this. I cannot relate to what you are feeling. We lived in the house that my parents still live in since I was 3 years old. That might be why I have such a hard time with change now in my adult life. My brother was almost going to move his family to Texas and I was not happy about it. They have since changed thier minds (my SIL got a new job and loves it too much).
I know when I was in 8th grade a friends family moved but she lived with me until we finished the school year. Do you have any friends you could stay with? Or would your parents not hear of that?
Good luck and I'm sure you'll make the best of what ever happens.
