I think anger is a natural and often healthy response. It is a way of processing negative emotion and the hardships of living with bipolar disorder certainly offer plenty of opportunities to experience negative emotions.
My question to you is, how does your anger serve you? Is it allowing you to process your feelings in a healthy way so that you can move forward, or is it dragging you down? Do you feel anchored or propelled by it? If it is working for you I say get mad. Sit with that for a while and let it motivate you to find your next move. However, if your anger is only creating more of the same and you find yourself dwelling on it, I would suggest looking at that a little deeper. You might find dropping the anger and navigating to something more preferable will serve your interests more.
Maybe you never ride the bus again, but maybe you can. I struggle with the notion that a few bad experiences mean you have to give something up completely. Sometimes that's the case, but I tend to lean toward hope for better in the future. I'm currently struggling with certain music triggering me. I have had to stay away from some very excellent jams with incredibly clever lyrics that I love. I know wholeheartedly I need to full on run away from it now because I cannot afford to trigger my brain into relapse. However, I maintain hope that one day I'll be dancing like a fool again.
Stay awesome Jane, I always enjoy your posts!
