Asbestosis....my lovely Dad...

Hi! My Dad has recently being diagnosed with Asbestosis.
I really want to help, because I just know out the somewhere is something that can help, either totally or for alleviation.

It hasn't spread through his body, he had a ct scan and it came out with this result
Through fear he refuses to go and have any more invasive tests, and frankly I can understand where he is coming from.
Through worry too he has become foggy, confused and at times bad tempered and downright nasty, which is so unlike him.

He can't sleep at night, he also suffers from Restless legs Syndrome, which of course just makes it all the worse.

I guess he is in a mess at the moment and I would dearly like some help and suggestions, if anyone can help, I would be truely grateful....thanks
