I am sure you will figure this out. School is your priority, just focus on that.
Im not sure what you are referrng to about non-witness moral standards- but college is a time for young people to try out new identities, behaviors, and lifestyles, styles. Dont judge people around you for doing so. Give yourself more room to explore who you are and who you can be. Stay safe but let yourself have some new experiences and spend time with other people. Try to focus on your commonalities, and dont be judgemental. (speaking from experience here) its best to lose your JW naivete as quick as you can. You will wise up, and that is a good thing.
remember that JWs compare higher education to shooting yourself in the head. When you are there acing your exams high on knowledge remember there are 8 men in Brooklyn who would rather you were not getting an education, and ask yourself why that can be, given your experience.
You dont have to go to anyones family worship night.
And one more thing, honey- there is no SAFE IN
its not safe in there. its a delusion.
