Only 24? That's not an adolescent, that's a grown ass woman. I can empathize with her having a terrible father who robbed her of a relationship with her real mother, but at the same time she needs to come to terms with her mother's boundaries and respect that a phone call once a week over the past year isn't enough to show up at Christmas with less than a week's notice.

I lost contact with one of my sisters due to geographical distance and my crippling social anxiety, nothing acrimonious. We've discussed plans to reconnect in person but I wouldn't expect her to invite me into her home on Sunday at the drop of a hat. These things take time, some more than others.
