studies, family, abroad studies, overall to overcome my dream

Hey, Italy would be better for you if you want to further develop your music talent. If you work very hard to keep your study and music balance, it won’t hamper your study much. Of course it is possible to study in abroad. You just need to be diligent and perseverant on it.
For the girl you love, it’s hard to say. You are so young that life may change a lot in the future. So just cherish what you own now. If you are excellent enough, and there is mutual trust as well as understanding between you and your future partner, family problems should be avoided.
