I’ve noticed anxiety about it usually comes from a couple key things, for us it was comments from family, the scale number and her not fitting into clothes she likes.
She already cut off toxic people, we threw the scale out, and we only buy stretchy clothes. Since doing all this she went from 190 back up to 240. I think it’s important to enjoy the journey of pampering her, focusing on goals can make it be not fun anymore. Make her O only when she’s really full.
