I've been pretending to go to college for the past 7 months
Is there a reason you aren't going to school?
Because my parents want me to go to college and I don't want to
You are lying to your parents by making them believe that you are attending college. You should be honest with your parents and tell them the truth or they will not trust you in the future.
It's my life, I'm still young, I can do what I please.
You can, and if you adult enough to do what you want, you should be able to be honest with your family. You shouldn't lie to your parents about things because they will always find out. You need to be more honest with them and what your plans on for your life.
