I did an images search of all the different looks for the drama/comedy faces, just because I'm such a visual person and yes bipolar needs its own symbol! Well, I found this, a beautiful necklace, with the 2 faces on it, I'm going to order one, wear the symbol around my neck, it reminds me of where I've been and how far I've come
