Health OCD

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?

I'm having awful stomach pain and nausea and it's really worrying me and scaring me

My OCD has been terrible the for the past two weeks. I have a fear that I will never be able to get out of the thought loop. I am hyper aware of my thoughts and it disturbs me. I haven’t been able to eat for 10 days. I force myself. I haven’t been able to sleep for more than a couple hours. Then I wake up and ruminate for a couple hours, until I’m exhausted. I’m also afraid I’ll never sleep well again. And I’m afraid I’ll never eat and enjoy my food again. I’m afraid I’ll never be able to stop thinking about this enough to enjoy my family ever again.
