My DD 17 has spent all day in her pjs when we don't have anywhere to go. I get so pissed off at her and I ground her and I take away her phone and etc. But she just doesn't budge and is in her pjs the whole day unless she had somewhere to go. I talked to my DD about this and she said she likes being in her pjs all day because she is fat and disgusting and she doesnt like wearing clothes. I have told dd she is not fat but she doesn't seem to believe it. I don't know what to do now?
