Big hug.
Step away from the phone. You and your D need to figure out the right level of communication (clearly, what you’ve got now is way too frequent and way too intense) and then you need to stick to it. A kid who is calling her parents for support is a kid who is NOT in the dorm lounge sharing popcorn with her dorm mates, and is NOT wandering the aisles of the activities fair looking for cool stuff to do and is NOT standing on line to get in to the lunchtime jazz concert.
The message to her is: Beginnings are rough and we know you can do this! If you’re feeling blue, reach out to the RA, go make an appointment at the counseling center. You will feel so much better in a few weeks. Can’t wait to talk on Friday- bye! Love you!
We all went to college when long distance calls were expensive, when we all shared a phone in the dorm, and most of my friends spoke with their parents once a week. I think it was WAY better than the current system. I’ve got friends who insist that their kid call once a day- and then they are a wreck because (choose one) the kid has no friends, the kid got a D on a quiz, the kids boots came from Amazon and they are the wrong size and cold weather is coming in 10 weeks, OMG, how is she going to get boots in 10 weeks?
It will get better. Set up a regular check in call a few times a week and remind her of her terrific coping skills. She will figure it out.
