I have the same thing when spring begins. Everybody has some level cyclothymic mood swings but it's about how far it goes. Maybe normal range would be to be able to hang on everyday life. Before i used to practically quit sleeping at spring. 3 hours of sleep were just fine for weeks, sometimes i could stay up all night doing something i considered most important thing in a world. Actually i was't ever really finishing anything i started. Also i was grandious, irritated and paranoid sometimes. Ignoring totally family and friends. Just inside my brain... BP diagnosis and meds has helped a lot since... Do you see any doc to describe your symptoms to?
