Hello and welcome from another small island, Tasmania.
There is a stack of information and support here, and a big family to back you up. Things happen slowly so don't stress about things.
I took the approach of treating GID as a medical problem when I came out to my family and didn't have any negative reactions, although my mum at 89 is still a little bemused by it all. My father passed away many years ago. If Gerry Adams and Ian Paisley can get along there is hope for us all. (Dad was born in Belfast so I appreciate what was involved there).
Karen.
