DD doesn't believe I actually love her

My 8 yo disclosed to me at bedtime that she often feels that me and her dad (divorced) don't actually love get; she feels like we are lying when we say so. This did not come after any kind of argument or disagreement, in fact we had had a nice evening together.I tell her frequently that I love her, and do things like hug/ hold her, talk with her, joke with her, do activities with her... all the things you do to show love to a child.She is currently being treated for OCD (overwhelming fear of being sick/ dying), but she doesn't feel like these feelings are related. I reassure her over and over that I do in fact love her, but she just cries says it feels like I'm just lying to her. She says she this started happening a month or two ago, and only really happens at night/ bedtime, and that during the day she doesn't have these thoughts. Overall she is a happy child, does well in school and has several good friends that she has kept in contact with since school has been out.What could this be, and what can I do? Obviously I want her to know and feel just how loved she is. via /r/Parenting https://ift.tt/3dov8nV
