After waiting and waiting to hear the first time, I learned that sometimes things happen and your case can get delayed (in Jenna's case they had staffing changes so her file sat for 3 months on someone's desk.) So now I know to call and ask for the status, and I would say i just want to make sure I've done all that is required.
When I completed the last task, I sent an email to the coordinator telling her this fact and that if they needed more information to please let me know. I have always emailed her with details about every appt I had and every other piece of info I could think of. I wanted to appear "helpful and informative" without seeming too pushy.
I am working really hard to change my mindset, trying to live more in the moment than in the scary future.
