Welcome Rachel,
You have found a great forum for information and support...there are buddy groups and challenges if on-line friends would help, or some use journals to stay on track. There are a number of threads here on cooking for the family when they are not LC. Look around the different sub-forums and find what will help you most. Are you an RN? Kelley Pounds blogs as a Low Carb RN and has an amazing amount of great advice linked on her pages. https://lowcarbrn.wordpress.com
All the best,
