Jay - sounds like a good idea. a couple of additional suggestions:
after you finish putting it all into words, let it sit for a day or two and then read it again with fresh eyes. you may want to edit or rewrite, add or delete some parts. it is often better not to shoot it off immediately because in the heat of the moment we may say things that can be minunderstood.
if there is anyone you trust to read it and give feedback, that may also be helpful. a more objective perspective can be very useful in finding out if you have communicated what you want to say.
it is a scary thing to do - but also very empowering.
please let us know how it goes.
all the best,
"Tell your heart that the fear of suffering is worse than the suffering itself... And that no heart has ever suffered when it goes in search of its dreams, because every second of the search is a second's encounter with God and with eternity." - Paulo Coelho
