Hi and welcome to the group. I live in a very rural area with a non-supporting family too. I find reading here helps a LOT when I feel like giving up. I get the reaction from my family that I can "try" to eat that way, but nobody else is going to, they are going to eat what they want, be overweight, diabetic heart patients, and think they are ok on this.
Read here, post often, and you will succeed. You have a baby to be healthy for now!
