Hi ya, its just nerves, honestly you will get all the counselling you need with Lighterlife and support on here is fantastic. As soon as you get into ketosis you will no longer be hungry and the counselling you receive will make you realise that the feelings you do have are emotional and there are ways to recognise and understand it.
I promise that you will be okay nad the time flys by so quickly, I cannot believe i have just finished my foundation part of LL and have lost nearly 4 stone.
Good luck, keep your chin up, it is so worth the effort in the end. Keep us posted xx
