every time i try to read a book i can't concentrate because of my thoughts

Does anybody else experience OCD while reading? I feel like i need to remember everything in my book. And i have a feel that i need to completely understand EVEYTHING in my book (even very minor things) and if not, i feel as though im cheating or that the minor thing is very significant and that ill want to remember it even way after i finish the book (just for the purpose of knowing EVERYTHING about my book) Also, when a character says some minor things i feel the need to understand it completely or i feel the fear that i didn’t understand what the character actually meant. If youve struggled with this please give tips on how to overcome it

I can't focus on anything but my thoughts. I'm so inside my head, and my mom always tells me to focus on my body and my surroundings, but I can't, or maybe I just don't know how. I try to, but it doesn't help. The thoughts are still there :(

For a while now, I've been having trouble concentrating... especially when studying... so I'd play the sound of rain or a forest or something similar to distract myself, and when I'd finish and turn it off... a pile of thoughts would come back to me as if they'd piled up on me!!! Anxiety, rituals... what should I do?
