Hello. please tell an adult that you trust and let them help you, not a jw. if you have a regular doctor or another sensible adult irl please confide in them. Someone like Flipper could probably help with background on the org that would enlighten anyone who is assisting you and help to understand the implications of your seeking help outside your family/spiritual circle.
Don't be afraid. If there is no God, no worries. If there really is a loving God in the universe, he has enough sense to know you are young and struggling and figuring things out. I am a believer in a merciful god. I know there are many who do not but how you believe is something that will evolve more than monkeys as you grow and learn in life. Don't focus on how you believe about God-it doesn't change whatever the reality is. Focus on what you want out of your life (next 80 years or so) and think of how to best achieve your goals for family, education, career. Not just until you are 18, but until you are at least 96. Your choices now all build up to the results. You need to make sure that you are not spending the next 80 years living the life others choose for you-make choices for yourself and the family you want, the life you want. Do it in an honorable way because what we do counts for more than what we "believe".
If your parents have anything worthwhile in them, I hope they will help you.
