Starting to think its more than just PCS, it's like my mind jumps from one thing to another and they aren't even close to one another on topics, and I don't hard on to these thoughts too long it's like ill be thinking what I want to do for the day and then all of a sudden something random pops in nothing to do with what I was thinking, is this normal? Could it be caused by my severe anxiety and over stimulating the brain or is it something more
