Everyone is in the same boat as you. A lot of us have put our lives on hold & sacrificed things.
I returned to Australia & left a great job overseas to focus on my application. It's the risk you take to achieve what you really want in life. No amount of worrying/stressing/emailing HR, will speed things up!
Patience is one thing i've learnt to have since applying a year ago!! If we are on the order of merit list & don't get a spot on course, we only have ourselves to blame, ie, not achieving high enough scores in the testing/interviewing!
Hang in there
