However, that is not the case; because once your son or your daughter is an adult, you will most likely just worry about him/her in a different way. It’s hard to let them follow their own path without enlightening them at every turn. Although it’s virtually impossible for any parent to completely stop worrying about their grown children, they can learn to loosen the grip.   

Talk to your friends about their experiences with their grown children. Friendly support can go a long way once you understand that others worry about their children just as you do. Together perhaps you can help each other to focus more on living your own lives by communicating with, rather than constantly worrying about your own children.

Realize that just as you have your own path, your grown children have their own path to follow. You can’t smooth life over for them before it happens. Chances are, your children already know they have your support. If they need your advice, they will come to you and ask. There is a fine line between guidance and meddling.

Understand that worrying accomplishes nothing other than wasting time. Life is going to happen whether you are fretful or not. It’s very likely that most of the things you are worried about are not going to happen anyway. If they do, your family will deal with it then.

Keep communication open between you and your grown daughter or son. The fact that they are adults indicates that they may understand more about what you are feeling than you think. If your let your children know how much you worry about them, you may be surprised to find out that you are not the only person in the family capable of giving excellent advice.

Remember that it’s not your job to keep everyone happy.

You can't expect yourself to stop worrying just like that. It's a learned process and will take time. Be patient with yourself.
