I live in a state like Michigan that also has four distinct seasons. I go hypo in the spring even though I am medicated. Right now I'm going thru the beginning stages which for me is irritability, sleep issues, and I'm talking a lot. Next I will be bouncing off the walls and starting a million projects. Last year looking back I was on e-bay a ton, but it didn't cause financial problems, but still way out of the norm for me. I was also in a mixed episode, long story. I really have no advice. I just ride it out, and my pdoc knows this happens to me so if it gets out of control I know when it is time to get into the pdoc. I just started seeing a new therapist and I talked about the irritability, and he told me to work on living in the now. I'm trying, but that might take a lifetime.
