Hello K V:
Wow ! big change in your life style. Since all of it is for you and your family take it positively and be strong. Your strength and good and encouraging words will motivate children to face this change as a good and adventurus part in their life.
However, you will be more tired at the end of the day. In case any of the children had something negative to tell,you will be more discouraged. But since you found a good job, you are lucky, just keep the positives in mind and for support lean on your partner. This is the best time for him to show how much he loves and appreciates you.
I hope you get all positives, Good luck, and remember take good care of yourslef, your appearance, health, food intake and exercise, balance all for yourself, as you are the one who has to go with lots of adjustments.
Take care and enjoy, the new life style.
