It takes a while to learn how to distinguish "normal" emotions and reactions from bipolar mood swings. I didn't really get it until a few months ago, and I've been diagnosed for almost three years. Sometimes life just sucks, and the bad feelings that come with it are merely situational. And sometimes extra energy is exactly that, not mania. However, you need to be aware that situational depression/mania can turn into the real thing if unchecked.

I know it's a pain in the butt to do "gut checks" every day, but it's necessary in the early going. When you get stable, you can relax your vigilance a bit.....it's not healthy to think about your bipolar all the time. You'll eventually find a balance, but it takes time and perseverance. Wishing you the very best.
