Tom, Billy,
I recommend counseling. This may (should) be covered by insurance and you can bring your partner along. .... which makes sense because it is a cancer related issue. As others have said, I now also have limited patience for some things while others are frustrating still and some may well remain so (referring to eating an speaking). Then again sanity returns and I realize that I am still here to write this, look at this board and see how much different cards one could have been dealt... Last night I had to cover, last minute, for one of my colleagues who had to undergo emergency heart surgery for a P. chem. lecture. A bit less than a year ago, they had to do this for me.
And no! I resisted to tell the class that this is "Potions" and that I am Professor Snape... although it was very close.
(... I am spending these mornings bottled up (hyperbaric O2 treatment) and tend to get a bit hyper myself after this probably due to 1) O2 and 2) extra sleep... so that may have some ramification on the above!)

It helps to take a step back. .... Someone probably needs to remind me of that too sometimes.
