I wanted to read this one before I read the next post.
I think that whichever way it goes, it will be a win. If you get it, it will be something you are well suited for and it will mix it up a little bit for you... then again, if you don't get it, you won't have to worry about exposing yourself to people you don't know.
Whichever wins, I applaud you for taking the plunge and seeing how you do with the interview and the unknown. I think you did well from the sound of things. Of course, my success may be different than what you consider a success.
Baby steps. I think you have done amazing, stepping right back to work as soon as you did and resuming life or trying to, keeping aware of your limitations, yet challenging them.
You may not think it, but, you are much more remarkable than you give yourself credit for.
