Frustrated

Today has been frustrating.  I was in such a brain fog this afternoon and it really got to me.  It isn't a new feeling or anything, I've experienced it for a long time.  It's really bad some days and I don't know why, but today it really, really has bothered me and made feel just 'stupid' to put it nicely.  For example, I was driving home and almost made the wrong turn.  Had my blinker on, almost fully stopped to turn and realized it was the wrong turn.  This is a road I travel all the time.  I turned off my blinker and kept going straight, fully knowing it was the next turn I needed to make..no biggie.  I am thinking the whole time, "Dummy.." and as I am thinking this, I go right past the turn I need to make.  It was like I was there physically but not mentally.  I turn around at the next road and in a few, I was home.  I know this is a simple little thing but I totally 'fogged out' twice in less than 30 seconds.  I just got really frustrated with myself because it really hit me how this disease can affect you.  Like I said, nothing new, it just seemed a little more real today and it sucked.  My gosh, we have got to find this tumor and get it out ASAP.
