there’s trouble a-brewing

my wife and i have noticed that i have changed since i have gotten back home; i’m a lot more distracted and my instant memory has gone by the way side.  i have a thought in my mind, and when i get up to do it, the thought seems to leave and i am left frustrated at what i was going to do.  i also have to ask my wife two or three times what she asked me to do.  it is very frustrating for me, and i am sure it is not easy for her.  i have also gotten a lot more irritable and quick to get angry/upset.  prayers would be nice.
