To be honest I only write when I am depressed and angry. I have never been able to express anything when I was feeling otherwise. I am not bipolar but borderline so I don't know it that makes any difference to you all. All I know is that I get my best expressions into writing when I am at the lowest of lowests (oops). I guess the difference for me is that I have never felt happy in my life, so all I know is anger, pain, depression, rage, fear and so on. At this point in my life and at my age, I can't even fathom myself feeling anything else anymore, but what I just described above.
