Questioning if you actually have ocd?

I hope this doesn’t trigger anyone else but I will be talking questioning your own ocd diagnosis Lately, I feel as though my ocd has been getting better! I have weekly therapy sessions and am on a dose of meds that I feel really help to alleviate certain symptoms. Because of this, I have started questioning whether or not I ever had ocd in the first place. I feel like a liar or a fraud. I deal with a lot of pure o ocd and I feel like a lot of symptoms can coincide with generalized anxiety disorder. I feel I might have both, but what if I was wrong about having ocd entirely? This really scares me, as I found a lot of recovery after learning about ocd, erp, and also from the community of others that feel and go through similar circumstances as I do. If I don’t actually have ocd I feel like I’ll lose all that. There’s another part of me that truly believes I have ocd. My ocd specialized therapist even told me I did, and personalizes my treatment accordingly, but what if she was wrong or I just didn’t explain my situation well enough. I feel like I oftentimes experience both obsessions and compulsions according to the different subtypes of my obsessions, but what if I gave myself ocd in believing that I had it? Like I was so convinced I had ocd that I actually gave myself some symptoms of it. What if this whole time it has just been generalized anxiety? Does anyone else have thoughts like these and how do I use treatment to combat it?
