Is this as good as it gets?

I thought I would come out of chemo and radiation calm, philosophical and patient, a better and wiser woman. Apparently not, I have been on Tamoxifen for a couple of months and seem to have developed a bit of a temper.  Not as tolerant of my husband who looked after me so well as I would like to be.  Also very emotional at times, I cried watching the second presidential debate at the thought of seeing a woman president ( happy tears). I too have much to be grateful for.  But some days I get angry.  It just seems to be the way it is.  Maybe in time the wisdom and patience will come.  I am not particularly happy either, maybe this will come too in time.  And please some energy would be nice too!  Good luck, I expect what we are going through is normal.  Karen
