Do i have Depersonalization-derealisation disorder?

I was suffering from anxiety recently and i am alot better now.

But i feel like something is off. I feel like I am not real sometimes and sometimes I feel that things around me are not real which pointed me towards dpdr disorder. I don't feel my personality. I tried practicing mindfulness in which I focus on a particular thing. During the meditation, I totally forget everything around me except that object or being ( even about me) and when I remove my focus from it, I feel like what was that feeling? Then I feel that either me Or others are unreal.

I started to feel like this since my anxiety started. Actually I have phobia anxiety which is that things around me are not real.

Some people told me that it is anxiety's symptoms.

Please guide me regarding my doubts.
