Can you obssess about recovery?

Hey guys! So I struggle with OCD, especially harm, relationship and moral stuff and I am somewhat recovered now. However, my current girlfriend has started showing signs of OCD but it’s abou5 something I don’t know much about so I wanted to see if anyone on here had thoughts about it. She is constantly thinking about food (when to eat it, what is healthy, what is too much, what is too little) and controls the thoughts by giving in and controlling her entire day around food. She don’t really know the feeling of being full. She never starved herself and always eats, but then she feels extremely guilty afterwards. Her thoughts do have to do a lot with her body image and not gaining weight but also not losing any either. Does this sound like ocd or an eating disorder?

When I was a child, before I knew this was OCD, I struggled with constant "magical thinking" compulsions (don't step on the crack or mom's back will actually break, etc). When I later learned this was OCD, it almost immediately solved it. Any time I got a magical thought, I would say to myself "that's just an OCD thought. ignore it." and it just stopped coming! Like seriously it fixed the magical thinking stuff forever. But of course the OCD has resurfaced in other ways. So naturally, I've tried to use the same strategy since I had so much success with it previously. But I wonder sometimes if telling myself "that's just OCD" is almost functioning as a reassurance compulsion? I hate how meta this gets. For example, I have ROCD that comes and goes. So sometimes I'll get a thought like "what if i'm still in love with my ex?" and then I'll tell myself "that's obviously just an ROCD thought" and will feel relief, almost like reassurance. But it comes back. So is telling myself that it's OCD a reassurance compulsion ?? It's just so weird because it worked so perfectly as a kid with the magical thinking thing.

Whenever anyone starts to feel like their thoughts are less triggering or they feel a moment of happiness/ relief OCD tells you that you want the thoughts back or you actually like having the thoughts and maybe thats just the person I really am? I feel like im going insane😢
