TMJD 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?

so i was on instagram and it came up with other signs of ocd then someone commented this doesn’t mean you have ocd now im stressed that its not ocd background - i had so-ocd for a few years then got treatment for it but am now on the waiting list for further treatment for other stuff but i dont have another theme which makes me feel like its not ocd my day to day life consists of touching the door handle every time you go past it or someone will die, and inability to send emails without re reading loads of times and getting other people to check because im scared i wrote something bad but the what if it’s not ocd thought is triggering me now and i don’t know what do

i’ve been dealing with this “thing” since i was 15. (i’m 23 now) if i have a bad memory that i have done when i was really young or just an intrusive thought i feel like i need to tell my mom or boyfriend. it’s been on and off ever since but since January hit it’s been an everyday thing about the littlest things. mostly about my relationship. an example is i was talking to someone random at my job and we were talking about taxes and when im in deep thought or just thinking i do a thing where i bite my lip (not in the sexual way) and i had a thought when it happened “was that sexual?” and i felt like i did something wrong and i went for a while thinking that until i told my boyfriend about it. or like my ex’s face has popped up in my head in the most inappropriate times and i feel the need that i have to tell him. (my ex was not a good person) i feel like im a prisoner in my head everyday, trying to justify thoughts or remind myself that its just a thought. i didnt know that this was or could be a form of ocd. it runs in my family but i’ve just never considered it being this. i always called it anxiety or depression but i always felt like it is more than that.
