Proud Dad with nervous daughter in DEP

My daughter is scheduled to head to GL in early July.    She recently had a bout of the doubts about the whole process.  But a frank discussion with her NC1 and myself seem to have calmed her nerves.  She's worried about loosing friends, missing out on summer fun before she heads out, and all those youthful things.  Plus she'll turn 18 during bootcamp.  I'm sure many parents have been through similar experiences with their "Future sailor".  I don't want to over do it in reassuring her, as it seems she's ready to go again.  I fully support her choice in the USN, and can't think of a brighter future for her.  Is there anyone out there whose "Future sailor" stared questioning their decision, who might offer some advice on how to continue giving support without being overbearing?
