Mine actually went pretty well. Part of that is because we are used to it; DD hasn't lived with me full time in many years and there are a few times I don't see her for a month or so. She's going to school an hour from me so I know I'll see her a few times during the year. And she's left her mom for a month or two some summers to spend with me, and gone away from both of us on backpacking trips, so she's not likely to get homesick.
Mostly though I think she will thrive in college. I'm excited for her, and of course pretty nervous at the same time.
We had a 3 hour window to move in, then she had to go off to a marching band meeting and practice. So there wasn't time for lingering or long goodbyes. We got everything in, unpacked, hung, etc, then a few minutes to unwind and check out the rest of the dorm, then it was time for me to go. She walked me to my car, and I watched her go back to the dorm and she never turned back.
It was nice that she got to move in a couple days early because of band, so there wasn't all of the stress and chaos of everyone else moving in.
She already has a friend on the same floor who she met in color guard tryouts, and there will be a dozen more she already knows there at practice, and another 400 or so in the band to get to know. So, I don't think she'll be lonely.
Those rooms are tiny! I saw some people bringing in small U Haul trucks, and I don't know how they'll fit in all of that stuff!
