Sounds like time for some tough love.
OP, tell your daughter to pull on her big girl panties and suck it up.
Remind her she #1 is in a military academy, and #2 one of the finest universities in the country. Oh, and #3, there were 4.37 gazillion candidates she beat out who would love to trade places.
All 3 of my progeny left home this past summer to attend a state university. All are learning some tough life lessons (like dad's bucket of money isn't bottomless, and he can't just swoop in from 350 miles away to fix all their problems). My son is in AROTC, and is learning that he's been a pampered, privileged child up to this point. He is figuring out in short order that he, and only he can make himself fit in ROTC. And my daughters (no military inclinations), though only a month into this ride have already figured out that whining fixes nothing.
I'm retired enlisted, but was stationed in Co. Springs for 7 years in total, and worked for numerous Academy grads over my career. Definitely the better officers on the whole, but, in fairness, I worked for a lot of good ROTC and OCS officers too. If your daughter's goal is to really be one of the top officers in the USAF, she needs to just get a grip, focus on the positive, and dismiss the negative.
Oh, and be thankful for what she has!
