anxiety about forgetting

does anyone have this anxiety abut how bad their memory is? like I would be talking to someone about even and i realize that i can not recall something that i known before. like my mind just reach some brick wall that it can't break. (I know weird comparison) This creates more anxiety and ocd about what the heck is going on with me. I am 32. I went to psychologist, psychiatrist, I even had MRI , CT SCAN BLOOD WORK, and nothing was found. It is very hard to talk to people as this disorder is hard to explain yet even harder to understand
