so my gf "forgets" to eat a lot and she has a very negative view of herself, especially her body. all she wants to do is lose weight. she does still eat but her attitude towards eating is very unhealthy and I'm worried about her. I'm worried that her goal weight will just keep getting lower and it will never be enough. the other day she even threw up her food. I try my best to encourage her to eat and be there for her but I don't know what else to do. any advice would be much appreciated.
