Frustrated means annoyed because nothing you try is working. Feel frustrated, frustrated by the delays, deeply frustrated.
The blocking is what makes it — you are frustrated when the way forward is shut, not merely when something is unpleasant. It also means unfulfilled, as in a frustrated ambition. Note frustrate, from the Latin for in vain.
