Yes. Feelings of guilt are quite common with PTSD. It is that disconnect you speak of Orange, that inhibits healing...yet remaining consistent at putting the right data into the brain will eventually connect... even when you don't fully believe it yourself, keep telling yourself that there really is no reason for guilt... even if you feel you didn't do some things you should have or did some things you shouldn't have, that is not logical thinking and needs to be blocked... at this point with ptsd, it's all bets off and you didn't do anything worthy of guilt.
