Is it normal to feel empty and having thoughts about your girlfriend?

I keep having this overwhelming thought of "I need to break up with her," however I really don't want to. It causes me so much anxiety when I try to fight the urge to the point that I'm bed ridden and unable to work. Is this normal for ROCD or am I just fighting my actual feelings?

I posted the other day and I'm still panicky and nervous around my girlfriend. It all started over a week ago with the first panic attack I've ever had while at the store with her. I looked over during it and saw her face during it. A day later a thought popped in my head that I should "break up with her." I fight the urge every day as it is not something that I want. I don't want to give up on her but the more I fight it the more my body seems to get stressed and anxious. As it stands right now my back is going crazy, tense as anything along with a tight feeling in my stomach and chest. It's causing me so much distress. Is this normal?

Is it normal to analyze every thought & feeling you have? For example. If I had a feeling like I wanted to flirt or if I felt like I wasn’t sad when my partner left for the night ETC. I over analyze these and they lead me to thinking I’m a bad partner or it’s not the right relationship. This scares me so bad Is this basically ROCD in a nutshell? It feels so overwhelming when thinking about all the different feelings and thoughts I’ve had over time
