Hello Eppie and thank you for posting your story.
You are quite right in your decision to attend college, and I hope that you will consider encouraging others, particularly other JWs, to give it a try. You are fortunate to have supportive parents; alas, not many JW teenagers have such and not only did these not get college support, but were even kicked out of the house for openly wanting to go on to a university.
There aren't too many posters here who believe that everything about the WTBTS is bad. They do have a few good ideas: no stealing, no convenience abortion, support for ethnically mixed marriages, obedience to parents, etc. But there are plenty of other religions that do all these and more: food pantries, clothing for the poor, housing assistance, care for the elderly, hospital programs, prison ministries, and many other good activities all supported by scripture and clear to just about everyone except for the WTBTS. A close examination of the WTBTS shows that anything that involves them spending money is off limits except for printing presses and ever more real estate.
If you haven't read it yet, I suggest reading _Crisis of Conscience_ by Raymond Franz, a former member of the WTBTS governing body. It is packed with documented evidence of WTBTS history and practices that they would rather have kept secret from you and every other thinking JW. Yet there is not a bitter or vindictive paragraph in the entire book.
Work hard at college; what you get out of it is proportional to what you put into it. It is a big investment of your time, but it also will pay dividends for the rest of your life.
