it took me a while to get here (still catching up on all the great posts), but am I ever glad I did! This is an amazing post and not just because your Yo Yo Ma analogy at the beginning had me laughing so hard this key on my keyboard now. Thanks for that. 
I also loved your explanation of bipolar - I now feel like I have a much better understanding of it. Your list of five tips for relationships is invaluable. Thank you so much for this post!
WOW !! EXCELLENT !! Thank you. BIG HUGS
Perfect words, regarding bi-polars in relationships.
