If you're not appreciated now, it's likely you just won't be. If bosses are giving you the run around, this is a clear indication of no promotion land. Sometimes mastering and overcoming the current situation is recognizing that it's time to leave the current situation.

For myself I can say this was an unsatisfactory reality with which to reconcile, however, it doesn't change the truth value.

Whatever your chosen path, I wish you the best.
