Starting around age six, I started to worry about my mom and dad dying. This was brought on when my piano teacher died that year. I was so sad at the thought of losing my mom. I used to lay awake at night thinking about how sad it would be to lose my mom.
When I was eleven years old, my mother died of breast cancer. Oddly enough, it was not the end of the world that I thought it would be. Life was very hard without her, but it certainly did force me to be strong and independent. I was still able to find joy and beauty in life. Still do. The saddest thought for me is the fact that my little brother, who was only two years old when my mom died, does not remember anything about her.
My children are six, four, and 19 months. If I died today, I can at least rest easy knowing that my older two will remember me. My husband is a very capable man, and I have no doubt that he would find good care givers for our children while he is working. I also think he would use good judgment if he ever decided to remarry. We have life insurance, a will, and trust. Everything beyond that is out of my hands.
I think if you have a plan in place in the event that you do die, you might feel a little less anxious. And you should communicate to your husband what you expect from him as far as what to do with the life insurance money, how you want child care handled, and introducing a new woman to your children.
And above all, love your children! Tomorrow is promised to no one. Your children will never forget you or the love and teachings you instilled in them :-)
