Welcome D. I hope you find that Primal will be a path for success, it was for me. Try to stick to Marks basic plan for a few months until you see how things work for you, and don't forget the exercise components. Don't see any height/weight numbers, but you've added back a lot of weight, may I suggest walking as a key element of your exercise--start slow/short, add distance/speed as your body adjusts. Get your partner out there with you, good for both of you and a great time for conversation and decompressing. Share your progress, I think that when you look back at your opening post in a year, you will very pleased with progress made. Take pride in making headway. Lots of posts here from Aussies, you should have "local" support!
The Buck stops here. I am responsible for my past and my future. So for today: I choose to be happy. I will seek wisdom. I will be a servant to others. I will greet this day with a forgiving spirit.
