Adult DD has lived alone in a city some distance away for little. She's very happy, and I am for her, however I find myself worrying more and more about her safety especially if she's out at night and it's late or dark. I find myself checking sm to see when she was last active, texting repeatedly to make sure she is safely at home, and have even phoned v late at night if she doesn't reply. She's been very understanding (I've always been a worrier) but I do need to stop as I know that it's not healthy for me, her, and our relationship. How do I do this?
