I agree with Millie. Really, you got the top 2 things, covered great. Being a Mom/parent, should be your first priority, and it sounds like you are doing great with that. Being succesfull in business, WOW, thats awesome, and quite an accomplishment. That one is usually number 2 on peoples list, some, without children, would say its number 1.
Maybe, you are having issues making friends. Well, just apply the skills you used to become a good Mom, and a good business person. It may come naturally, after that.
If its spirituality, that you are looking for, or not having an easy time adjusting too, that may be a bit harder, but it can be figured out. Thats part of everyones own personal journey. You should never let the org/GB, dictate what your spirituality is. Its between you and Jehovah, or you and the universe, or you and your own peace inside.
Dont be so hard on yourself, you are probably doing fine. Yes, we can always do better, but we have to take it one step at a time. Even 8 years, is not neccessarily a long time, in the scheme of life. If you accomplished being a great Mother, and a powerhouse in business, in 8 years of being "out", you should COMMEND yourself, and be PROUD.
