What Did I Get Myslef Into?

i am 15 and currently going to a modeling school in Los angles called barbizon. i sign myself on this website and i really didn't think nothing was going to happen i just did it for fun .a week after i got a phone call for a interview.so when i got there i found out it was a modeling,dancing,singing,acting school. i had no idea what had got myself into. i got accepted and my dad pay for it. At that point i wasn't thinking and soon enough i became part of the school.Modeling was the last thing i ever wanted to do in my life. i now feel must show my dad that all that money wasn't for nothing.i need three more classes till i graduate. i fell so dumb for not saying no when i had the chance.i have not booked any jobs so far like the other girls in my class which really sucks... :/
