homesick

Hiya. I am from England, I have lived abroad for about around 6 years now. I live about 8 hours (by plane) from my hometown. When i first moved, i hated it. i was always wanted to move back. It stopped after 2 years. And now, about from the beginning of December I've been very homesick again, it's been getting harder and harder and then the past few days I've been crying all the time, I've been having fights with friends and being bullied which doesn't make it easier. I only have one person that i have talked to about all this, and she lives in England. I've never felt so lost and sad in my life. I am usually am homesick once in a while but nothing like this. My mum and dad enjoy life here but i feel like they don't seem to care about how i feel about living here. Like i said I've lived here for 6 years, and i feel like it's enough and I'm ready to go home. I'm so upset and i don't want to tell my parents about how i feel and that i want to move because if they say that we cant move back i don't know what ill do, I'm scared to face the truth. I've gave them hints that i want to move back but thats about it really. Why did i have to move away in the first place :'( is there any way I can persuade my parents into moving us back to were we belong?
