Replying to Give it all up ?

I'm having a wonderful life, loving parents who pay for me, good friends, quite good marks, roof above my head, food to eat etc, but I don't feel happy. For a long time i'm thinking about giving it up, take my money, stuff and go abroad at the age of 18( I live in Poland). I KNOW WHAT YOU THINK, He's stupid young noob, who knows nothing about life, but i think that only then i can feel happy. I haven't spoken to my parents about this, couse they'd get mad. They want me to choose conformist lifestyle. Study-home-family etc. But I just wanna travel, ski, meet new people, having fun, living live. I listen to punk music, read beat generation books, Im intereted about counterculture, and I always admired people who were in some way different. I feel like part of family, here on NS, so please DON'T HATE ME. I just wanna know if it's possible and what you think about it. Any suggestions what to do before that ? What are the consequences? How much money do I need to live first few weeks ? K+for understanding :)
