I experience shifts in my mood, sometimes throughout the day. I would wake up feeling depressed, life sucks, I’m a worthless pile of trash. Feel like this for most of the day and then by the afternoon I will feel like I’m on top of the world. I’m the best, Im good looking, people would want to be me! From what I have read, it seems that bipolar episodes last for months, but these mood swings for me change throughout the day or every few days.
