when you guys go down a spiral does your brain just keep going back to the same thought no matter what you are doing?

Please help I am having the worst spiral I have had in 5 years. I am doing so bad to the point I could not even sleep. I’m so scared, anxious and confused. I did ocd therapy for a long time and my therapist told me I was doing so well I needed to stop. Which I was until about 2-3 weeks ago it started back super bad. And now as of yesterday the intrusive thoughts feel more definitive. They are making me spiral, it literally feels like my brain is jumping from side to side. I love my boyfriend more than I knew was humanly possible. I haven’t lost my attraction to him, not that I know of… I don’t want to break up with him bc i love him, I think he’s hot, I want to marry him but I’m terrified that I am just lying and that the feelings never were true! I don’t know how to make it stop. I tried all night not to research and I had to give in. 😭 this is hell

Anyone else have repeated thoughts that play that are negative. Basically a back and forth of you telling yourself you don't want X to happen but having a thought that slips saying you do. Like being stressed out one day and saying "man I wish I were dead". But instead of letting it roll through your mind and thinking nothing of it, you obsess if you actually want that outcome for yourself and you are now scared you'd fatally harm yourself whenever you feel anxious or stressed even though you know you wouldn't. So now I repeatedly get I wanna die stuck in my head and I feel the compulsive need to say no I don't to combat the thoughts and it happens throughout the day and even when I wake up.

I’ve recently been having the spiraling intrusive thoughts coming up out of seemingly nowhere. Well not exactly nowhere, having some relationship issues but the thoughts will just randomly show up when I’m clam home reading a book.
