Thanks for asking.....
I came to HK, helped gather my sons belongings and sorted frieght back to Australia.
Got his wife into a mental health clinic after a diagnosis of post natal depression.
Got him onto a mental health programe.
Leaned that he had been diagnosed with Adult ADHD some years ago but that was not shared with his Mum and me.
Apparently ADHD drugs are not available in HK which led to self medicating on other (prescription in Australia) but, over the counter drugs in HK .
Over medicating left him often in an almost zombie like state, unable to work or pretty much do anything productive. He didnt recognise this in himself. His life just fell apart.
Although recovering now, back on the meds, he struggles with acute axiety so will take a bit of work to rebuild himself.
We'll get there.
