Can ocd be episodic? I feel like I’ve had episodes of it throughout my life but periods where I don’t experience symptoms

Definitely. I go about a year or so in between then if I get stressed by any little thing it comes back in a huge wave x

Definitely, I had a period where I had only one compulsion and it was a time one so my parents never noticed it so they thought that it went away even though it came back later.

Yes. My themes have changed many times through the years. I have had years where things aren't that bad. But then a new theme starts. I have had OCD since I was 8, but I didn't know until last month. I was diagnosed at 45.
