TwinOtter.....I am so glad that you had the presence of mind to make a call---a call to anyone----and, I actually think that it is pretty smart of you to think of calling AA when you couldn't find an alanon place.
I do know what you mean about the "shaking with anger". It is like your brain is so flooded with that emotion, at the time, that organized thinking about anything else seems almost impossible.
You did the absolute most important thing----you talked to SOMEONE.
Congrats on your action---and, always remember that if you ever have a similar feeling in the future. It is a valuable think to know.
