I did full QT course for my family of 4. Lost 100K HKD on it and, probably, 20 years of my lifetime due to nerves, stress, severe depression and strong hit on my physical health as a consequence.
I feel for you, but unless it was an emergency, it's hard to sympathise with such a stupid decision.
(And I say that having friends who did the full 21 says just so they could spend time in their home countries during the summer)
