Hi and welcome!
Why not use a free tracker like paleo track or fitday? Also you do not need to buy grassfed everything if you can't afford it. Yes that is the Primal ideal, but many of us do not go that route.
You are in the right place. Do you have the Primal Blueprint? Please make sure you are following PB by the book and not the sometimes random forum advice. I would read some journals and find others who have similar issues and life situations. Make friends here. No one can go it alone. I am also a Christian and though I believe that God is there to support us, we also need other people.
