FBL, heartfelt congratulations on the good report at the doctor!
I've found that I get angry much more often in sobriety. It's because I'm more involved, engaged, and paying attention. I have to work at acknowledging the emotion, identifying the problem & my part in it, resolving the problem (if there really is one) and letting go of the emotion. Sometimes it's just a matter of telling it to someone you trust.
A Poison Tree
I was angry with my friend;
I told my wrath, my wrath did end.
I was angry with my foe:
I told it not, my wrath did grow.
And I waterd it in fears,
Night & morning with my tears:
And I sunned it with smiles,
And with soft deceitful wiles.
And it grew both day and night.
Till it bore an apple bright.
And my foe beheld it shine,
And he knew that it was mine.
And into my garden stole,
When the night had veild the pole;
In the morning glad I see;
My foe outstretched beneath the tree.
