Oh frenchy! I would say even though it's hard for you, you have to let her go. I know it's very scary but the feeling of accomplishment and confidence she will have be outstanding! Most likely she would go to training and then be deployed somewhere within the states first. I have several friends that were/are in the armed forces. Most of them marines, but some air force as well and some are still active. Try not to owrry too much, and look at it as though your daughter is wanting to do something very important for herself and others.
*hugs frenchy*
If you can't handle the thorns, don't crave the rose!!
