The feeling of being Sungshin freshman..

It's difficult to write my feeling about my freshman life in Sungshin. Well, to say frankly, I was disapponted. When I was high school student, all the teachers said that "If you become the university student, you'll be thin and have a date with your nice boyfriend" and whatever...they told me that "university" means "dreamland", and I studied hard to enter the university. Although my dreamschool was not SSWU, I felt confidence that I become the university student. And nowdays, I feel empty. And sometimes, I recall my highschool days and wanted to go back at that time because highschool students' life is simple - only study.
In highschool, the only thing that I have to do was studying hard. But nowdays, my life is continuity of trouble - Who am I and Where I am? The university was not a dreamland that I imagine. Perhaps it's just a subcontractor of big company - to get a job like the hand-written poster at K university. Also, tuition is too expensive - Brightning in Global generation or having a debt.(In Korean, G-세대로 빛나거나, 빚내거나)What's more, I have a question about my aptitude. My dream was being a diplomat at first time, but when I studied world history at highschool, I thought it is not an appropriate job for me. Next was being a copywriter, but nowdays I think my ability is not sufficient for that. What am I have to do? It feels like that becoming Alice in Wonderland. But most important thing is, I feel an inferiority. When I met my friends who are students of Yonsei or SNU, I feel small. In highschool days, I thought now we're wearing same school uniform, but in the future, if I would be sick and go to hospital, one of my friends can be there because she is a doctor. And If I travel abroad, one of my friends can be there because she is a diplomat. Then, How about me?? Can I laugh with my friends at that time like in highschool days? And I'm so sad that thought is likely to actualizing.
