Not sure I have it but I do have a memory

I have been discovering things about how my brain works for a while now. I see lots of symptoms that I display that allude to OCD But I’m not diagnosed and not trying to self diagnose. However on this discovery of myself I am getting memories of things that would happen in my head that seem very strange.

When I was in 5th grade I was homeschooled for the year and had a math book I had to do daily. I hated doing it because I felt pressure on what I was doing even if I was alone with nobody monitoring me.

I would be working on my math and would answer questions and then worry if it was right or wrong because I would obsess over the fact that my book knows exactly all my answers and the math book was watching me make any mistakes and would laugh at me.

I would always answer a question then immediately check if the answer was right or wrong and if I was wrong I would quickly change it and pretend that I actually knew the answer and I was “just kidding” with the wrong answer so the book wouldn’t make fun of me. I never heard any voices really it was just a mental game. Idk maybe I’m crazy but that’s just one example that sticks out to me.

I noticed I did it with a lot of inanimate objects growing up. Thoughts?
