I know it's not much consolation but I think you made the right decision to stay with your schooling. You had already committed yourself to that and it was the course you were meant to take. Sure...it's frustrating to think about what "could have been" but it does no good to look back and speculate. You may or may not have gotten a more permanent position. The important thing was to finish your education. Something will come along and maybe even something better than a gig with Star Trek. Just hang in there. You may want to consider going back to school and work toward a masters. It would make you more employable.
