I am sorry you are struggling with that. It's hard sometimes I think to figure out what is causing what, but I am sure there could be a combination of factors. I have a much stronger urge to workout when my anxiety is up or I have excess energy, but when I was still dealing with an ED and exercising to an obsessive degree, it really raised my anxiety if I missed a day. They sort of fed off each other I think, because then I would start to fixate on not being able to workout because of my anxiety and also think that was the only way to deal with how I felt. I would also start to feel like I was bloated or something from not exercising, but was probably just obsessing over how my body felt. Can you try something else like meditation, cleaning, yoga, or distracting yourself with a mentally enjoyable/engaging activity? I think redirecting the energy could be useful. It often helps me.
