Substance abuse ocd

That’s kinda my question. All my thoughts feel so realistic and so now I doubt if they are ocd and if I just can’t make my mind up about something and I’m using ocd as an excuse or something idc I feel like this post is word vomit.

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 the need to confess that I was unfaithful to my girlfriend (even though I was not) because I drank too much Saturday night and don’t remember every single second from my evening. My OCD immediately goes to that I cheated on my girlfriend and I need to confess my sins. I know it’s only OCD, but the thoughts are extremely strong. Any suggestions? Thank you, community.
