Is there anyone there supporting you mate? (Crew or medical staff)No. Not really.
Difficult coming to terms with the suddenness of it and the fact she isn't here
But having you guys on this forum helps
Are they dealing with any arrangements for you ( cutting short the trip, for example and managing your needs and expectations)
You need support right now and I hope you are not just being left to deal with this on your own. That would just be too overwhelming. Unless, you feel you need time alone, then that is your personal choice and should be respected.
Take care mate.
