Hi there, it does sound pretty normal, because I do believe that you have to keep it in your thoughts all the time, other wise, I tend to lose focus. However, the issues you have had in the past will be the main reason why your partner is concerned for you. It is only because they cares for you.
Sometimes when you are new to slimming world, it can be hard to not feel guilty when your eating something because slimming world is so amazing, it takes time to believe that you really can eat so much and still lose weight.
