It was very interesting for me too.
I dont get the "manic" side, but I can be rather "over the top" sometimes. Which raises the question "Am I just Uni Polar? and if so, which bloody pole am I? I have an affinity for Polar Bears (north), but I also dig penguins (south) :-)
I am very glad that Mr Fry repeated that his suicide attempts were not a cry for help. When I hear that phrase it makes me angry. Help is not what is on the mind of a Depressive - he or she can see no help, and doesnt feel worthy of help even if any were to hand. Its all very complicated really, and beyond my means to explain, but that programme went a long way towards doing just that.
I have been on anti-depressants but have stopped taking them as I feel that am better coming to terms with what I have on my own, without being drugged.
If I am wrong, you can read about it in the Obituaries :-)
