I am 17 years old and have been counting the numbers of letters in any sentence that runs through my head for as long as i can remember. Any phrase i read, hear or think i count the number of letters. I then obsessively organise the words into sets of 10. If they do not fit into sets of 10 i will change the sentence or add punctuation. I like my words to add up to multiples of 6 with 48 being my favourite. I always thought i was weird for doing this but its good to read about other peoples experiences. I drive myself crazy with this but i dont know how to stop. i think i have an overactive brain and i always have trouble sleeping. I panic if volumes arent at a multiple of 5. Ive also got a strange ability to remember the dates of events for everything as far as 3 or 4 years back. This memory has been associated with aspergers and autism. Do you think i should seek medical advice for this?
