What are you scared of at this moment? There's a good lesson to be learned from this IMO.
1. You're too young to be having sex IMO
2. Too young to be drinking unless it's a glass of wine with your parents consent at their house.
3. Don't attend unsupervised parties - someone could easily slip a date rape drug in your drink.
4. Know that you're free to leave a party or situation where you're not comfortable.
