It's heeeere....
I got an email from my therapist this morning, just with a link about work.
I wrote him back and said I came out to my boss while on travel with him... that everything went great and my boss wants to learn more. I also asked about the status of my letter (11 days 'til my endo).
He said he was already in the process of writing it this morning (he had previously completed the outline with all my info).
I just got the letter!
