There is literally step work outs on YouTube she could do. I sometimes do them when it’s absolutely pissing it down and I dont feel like getting soaked. There’s dancing ones as well. It’s a good, easy and quite fun way to get some steps in when you can’t go outside. Although, I do it because it makes me feel better. She is clearly doing all of this for other reasons to do with her ED.
It wouldn’t surprise me if after today she “fell of the wagon” again, these things tend to happen every few months with her. She’ll say she was in a bad place and she’s starting again etc etc. Clearly what she’s doing isn’t working so I don’t understand why you wouldn’t seek a professionals help at this point to aid you in the best way to recover?
