Thank you for posting this. It is a hard area to discuss, but important to hear others going through the same thing. I am in my 28th month of PCS recovery and have noticed a definite change in my patience level. I get to points where I just can't deal with things and have to remove myself. Usually I have a headache (they have been constant) and there are loud noises or bright lights. My temper goes from okay to rage in a few seconds, surprising my husband and kids. It is hard to separate the argument from the intense anger, but it has been happening for 28 months now. I tell myself it is pcs not the person I am talking with and try to get away from the situation before I do permanent damage. I can't stop the feelings of rage, but I understand them better now, and it helps to know I'm not the only one experiencing this.
