Congrats to you CitizenofEarth. Good name by the way.
Eighteen and you already know the truth about the truth!
I wish you all the best for the rest of your life.
Try to stay on good or at least decent terms with your family if possible.
Remember however that your brain has not yet finished growing (that happens in your mid to late twenties). So a good education is important now it can provide a proper foundation for your future. A practical use for your education needs to be understood. I have seen far too many young people get side tracked and finish or leave the higher education system without any marketable skills.
Also make sure you protect yourself from excessive alcohol, drugs and the other traps that can turn you sideways.
Use this forum because while we may not be the youngest group of people......... collectively we have thousands of years of experience you can tap into. We are not limited to just JW interests.
Your parents brought you up telling you that the end was just around the corner that's the JW short game. Now you will have to adjust to the long game........ an additional 70 or so years to live your life. Different rules........ different goals.
