WHAT SHOULD I DO?

         i was confused and worried about my future, especially during college later. Is it normal to have this feeling during high school period? (correct me if my english is broken please). Sometimes when i was excited to study abroad, i thinked that i'm gonna live in a new life,new country, far from my family, new friends (if i could). So i say to me "if you scared, then you have to do it", it makes me excited again.

         After that, i tell my older sister and she said "yeah just go, you can do it". OMG i can believe that she let me. Then she asked about my study program that i want to study, so i tell her. She was surprised, also me. She said "better you have college in this country but different city" my country have a study program and also they add some of my religion basic knowledge. So i agreed and searching the university, with my study program. I was found it, and my older sister agreed

         Now i'm nervous if i could do it or not. I don't have my parents consent yet. I'm afraid my parents don't allow me to study in another city
