Can someone be fine then out of no where anxiety hits them with fear, worry, sweaty palms, and then ocd intruaive thoughts all randomly?

These past few days I was fine. Minimal intrusive thoughts ,no anxiety etc(to add I'm on medication so maybe it's starting to work although it barely is 2 weeks) and today I got a sudden wave of anxiety and it started latching on some thoughts like" what if I'm in denial and I wanna break up with my bf? And what if erp doesn't work for me because I actually wanna break up with my bf?" But they didn't really stay long usually those thoughts would make me spiral for days or so, now they lasted for some hours. And now I'm trying to trigger myself into being anxious again because if I don't it means I don't have ocd and if I don't have ocd it means I don't love my bf and if I don't love my bf it means I have to break up. Idk if it makes sense but the lack of anxiety makes me wonder if I actually have ocd or not.

I started dealing with OCD when I became fixated on health issues, particularly the fear of contracting a life-threatening disease. If I experienced any kind of medical symptom, no matter how small, that even remotely hinted at something potentially fatal, it would drive me crazy, and I couldn’t stop obsessing over it. Then one day, I started having intrusive thoughts about accidentally hitting someone with my car, and I would end up driving in circles to check if I had. Eventually, I found myself overwhelmed by a flood of new obsessive thoughts and compulsions. One day, while I was at the park, a squirrel came near me, and for some reason, I felt like it attacked me. I Googled it and learned that squirrels could carry rabies, which spiraled me into a deep fear of rabies. I became consumed with the thought I received a bite from a squirrel, raccoon, or bat any time I’m in areas that trigger me. It started off only being inside then transferred to even being in my own home. This made me obsess over every physical sensation in my body, compulsively checking to make sure nothing was wrong. One compulsion that I hated the most would to be putting rubbing alcohol on me to make sure that I had no open wounds. Every day feels like I’m walking around in a fog of anxiety, constantly worrying that I won’t even make it to old age. Sometimes, it gets so overwhelming that I just want it all to end. It stresses me so bad at times to where my brain feels like I’ve been studying all day.

So, yesterday while I was laying in bed, I was relaxing when suddenly I had an intrusive thought about someone, but the thing is that it brought me a sense of enjoyment or calmness for a few seconds before it went away. Once it did, it was only until hours later when I realized what had happened and I began to freak out because I'm reading everywhere that when someone experiences this type of thing, the anxiety happens shortly after the enjoyment or "false" enjoyment. Can OCD do this?
