I do both. I’ll write the same word (or pattern ) over and over until it fills the paper and sometimes I’ll write it backwards or upside down. I can’t stop until it’s full. It doesn’t bother me that I do it.
I can get over chatty in social settings to the point where I walk away and I can’t remember everything I said or wishing I hadn’t said stuff. That bothers me a lot. Then paranoia sets in.
