What does this mean for you, etc, etc, etc? Are you planning to come back at a later date to complete your HSC?
And yes, it's nothing to be jealous of, especially if the reason was illness. One girl did it because she couldn't "handle the stress" and broke down after trials (may be quite likely, but she's in Newcastle med now, so make of it what you will), while another from my year, who's completing her other half of her HSC this year, had cancer. I don't think anyone would fancy having a breakdown, or having cancer, for that matter, over just going home earlier.
