Pain and 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?

It started when I became an adult, and started receiving my mental health diagnosis. I hyper fixated on each and every action I did and how it could be related to my diagnosis’s. It then lead to fixation to my physical health — making appointments and seeing every specialist I can to rule out every possibility. I currently have been suffering with obstructive sleep. I woke up the past few days with severe pain from the lack of sleep whilst believing I was oversleeping. Luckily my fit watch tracks my sleep cycle and it turns out I am not receiving any sleep. I had an extreme panic attack — bursting into tears on the phone with my mom wondering what this case might be. She told me it could be sleep apnea and that a simple sleep study could figure this out. However, knowing my family history I made appointments to every specialist I can to make sure it is nothing serious. The unknown of health can be scary to me. Watching my mother suffer with her physical health chronically since I was a child lead me to be very conscious and aware of how my body is functioning. This morning was one of the worst moments of physical pain. I should just take one step at a time with the sleep doctor instead of taking measures to see every specialist that could pertain with this issue. However, that is very hard to me. I don’t want to ever wake up in the pain I was this morning. Does anyone else suffer with health-related OCD? And if so, how do you find a sense of ease during moments like I expressed?

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