Hi noonehome, I understand that you feel that your viable options are limited and very undesirable. Since you are attending a university/college go to the campus health care services and inquiry about counseling services that may help you to more clearly assess your options. If the campus services' counselors are not familiar with the WTBTS and other dangerous cults, give them links to www.freedomofmind.com so that they can provide you with better service.
The elders have no power of you unless you give them that power. Just thank them for expressing their concerns to you, tell them that you are very busy and will contact them when you need their help.
Make your plans to enjoy the rest of your life. Your plan should include making more non-JW friends and doing more non-WTBTS activities that give you opportunities to make more none JW friends, so that when your JW friends start to shun and avoid you, you will have a good support network of unconditional, non-JW friends.
As far as your friend is concerned, why give conditional friends power over your life? Unhealthy relationships will remain unhealthy for you as long as you allow them to continue. Please watch Steve Hassan's video How Big is the Phenomenon of Undue Influence? (2:01) about what consitutes unhealthy influence in relationships.
Peace be with you and everyone, who you love,
Robert
