Hi Alan,,you are doing very well already to come to your conclusions at your age. Take it one day at a time. You don't have to rush, you have time. But correct, don't get baptized. It will make it more possible to keep your relationship with JW family to an extent for now. You may need family support yet? Will it be possible to go away for further schooling, on scholarships/loans. Do you have some extended family not JWs that you can get some guidance?
Again, glad you made it here. It's good to see you already have made concludsions that the JWs are not the truth and you seem to be well-aware of what are your needs as an individual. So many best wishes, you have many good positive times ahead in your life.
