I don't want to leave them :(( What should I do?

Hy! I am a 22 years old boy. Now I live alone in my country, there where I lived before with my parents. I mean with my father, my stepmother and my stepbrother. Until some months ago I didn't love my stepmother and my stepbrother very much. But now we understand very well with each other. And my stepbrother is so sweet...He is 1 year old. Last year, in July, they moved in another country. I remained here because I am in the last year at the college. I will graduate in July. Here, in my town, also live the grandmothers, my mother and the other brother. But with my brother and my mother I don't speak very often. They don't call me very much. Now... After graduating I will become a translator. I would love to be hired at a publishing house and translate books. And for this I work from home, My father and my stepmother want me to stay in my country because they say that it is better for me and probably I will have more luck to find a job here than in that country. But I want to live with them, wherever they will be. I miss them so much... Every time when thy leave, I can't resist not to cry a little after that. :( What should I do? What do you think?
