Absolutely! There were times when "anger and frustration" were my two middle names. Really, anger and frustration can symptoms of my hypomania/mania/mixed episodes or they can be normal emotions born from stressful situations (stress involved with having a major mental illness, work-related stress, and all others we deal with in life). Though it isn't a major personality trait of mine, I can't say that I don't have a bit of a temper, sometimes. Everyone in my family does. That contributes, too.

Bp Magazine (or bphope.com) has had an article about bipolar disorder and anger in the past, and one new one just popped up in my email this morning. If you're interested, find it at Anger Management: 7 Tips to Calm Your Rage | bpHope.com
