You don't need me to tell you this, but you're in a tough situation! I thought of 3 things (don't know if they will help):
1 -- Have you ever brought this (EXTREMELY IMPORTANT) issue up directly with your parents? No matter how unpleasant a topic is, it's almost always better to put it out there and hack away at it than to have everybody walking on eggshells and internalizing stress. (Please understand that I have never been a JW so I don't know if this advice is workable or not...)
2 -- Is there any way for you to get support from your friends at school before you graduate? Or attend a church with one of them instead of going to the Kingdom Hall? Do you have any good people to rely on outside your family? Or maybe is there a church within walking distance from where you live since you have no car? (I know that going to a non-KH church is frowned upon in WTS land, but I think that would be sufficiently overt of a gesture on your part...)
3 -- I have to say I disagree with one part of your post:
...and clearly, waiting on God aint doin' diddly squat.
God IS with you and is sovereign over your whole situation. He knows exactly where you are and knows what the next step is. I am in a bit of an uncertain place in my life right now as well, but even though I can't see the next step, I know and believe that God is already there, arranging things favorably for me down to the very last detail. He has come through like that MANY times for me, and He is faithful and loving to those who fear Him! (end of sermon
