Advice on OCD confessions during my so far 2 year relationship

So I recently had a lot of false memories and worries that I didn’t know were OCD until too late, I confessed them all to my girlfriend and she took it very well and was very supportive during all of it. My problem now is I feel so stupid that I brought it all up because I soon realised it’s all fabricated in my mind and never happened or never happened the way I thought it did. She’s aware of it being OCD now and knows it’s all not true but told me she feels a little down because it was very intense for the both of us. I feel like I’ve changed my perception of myself with her even though she told me none of it matters. How do I get comfortable with the fact I basically had an episode and now feel like a dumbass, I used to be the strong one and now I feel like the weakest of a beautiful pair. I love her very much and she tells me she loves me every day but I still feel guilty for putting her through all this stress.
