Nerves before accepting appointment normal?

It's been months since we've posted, but DD has official appointment to USNA along with several great backup plans. It's been USNA #1 for years, but now that it's getting close to decision time and other options are coming forward, she is getting a little nervous. Nightmares about plebe summer, worries about the future, stress of academy life, service assignments, etc. She's had a lot of USNA experiences (STEM Camp, NASS, and CVW), so she's got a pretty accurate view of life there.

So many...
