Diagnosed with Retrospective OCD – anyone else?

I’m trying to understand how it shows up for others, and how to tell the difference between OCD and GAD.

For me it’s like this: • I replay past conversations to check if I said something wrong • I worry I’ve hurt people emotionally and need reassurance to calm down • I question if I’m actually selfish, fake, or just unaware of how I affect others • I re-read journals or messages to “make sure” I’ve understood things right • In my relationship, I get scared that I don’t really love him – and then I either avoid everything that reminds me of it, or obsess until I feel sure

Anyone else relate to this? Would love to hear how you deal with it.
