Being a JW you do not have to make too many decisions, they will make (prescribe) the decisions for you.
I do not think anyone can make this decision for you, you will have to make it four yourself. For me 'crying pretty much every day' is a very strong indicator of needing a change!
But are you sure you have considered all your options? There are usually always more than two.
Are you sure you can finish college if you stay? What if the next study article in the WT tells publishers 'not to pursue higher education inspired by Satan'? (My experience shows that by all means go for a higher education!) What I am trying to say is that do not be so sure you can go through with it, get your degree and job and then leave. Also do not underestimate the brainwashing capacity of the WTBS if you stay, I have former friends who are aware of the lies and know the WTBS doesn't really care about their people and still remain. It takes courage to leave, if you stay the brainwashing can get to you.
A little while back I had a really bad job, I knew if I didn't change it would affect not only my mood, but would start nudging away at my health. So I jumped into the unknown and this jump forced me to find new ways, explore things I haven't before. The first try didn't work out well, had to change again, but now I'm finally doing okay.
The best advice I can give you is to BE TRUE TO YOURSELF! Do not pretend to be what you aren't!
