It's not really up to your friends or family, though. It's your decision. When I first went vegetarian, my family didn't support me, and I ended up just eating salad and not a whole lot else. Over time, though, they've come to see that I'm actually serious about it, and now mum buys me vegie burgers and so on.
Maybe go into Woolies and find out what is there, I'm sure that there'd be SOMETHING, small town supermarkets (that aren't even a brand name) stock tofu and some variety of vegie burger (they also sell them in the deli section of some supermarkets), so just go and have a look around, see what's there, then when you tell your family, you can say but LOOK, TASTY ALTERNATIVES!
As for your friends... just stick at it
