Yes sometimes i cycle several times in a day. One day I woke up feeling on top of the world, was cleaning house and feeling very euphoric since this was a slight hypo manic morning. I cleaned all the bathrooms in the house scrubbed tubs toilets and floors. Then took a shower and left my house to go visit with a good friend. By the time I stepped in her office at work I had a huge feeling of anxiety come over me, my heart started racing and I had to cut our meeting short and go home to the safety of my bed. About an hour after getting home I sat up out of bed and just started crying out loud like a child would. I felt my life was completely meaningless and I wanted nothing more than to die. I started making plans and telling myself how much better off everyone in my life would be if the burden of my bipolar didnt affect their lives anymore. This went on for probably 45min to an hour. Then my husband got home and we had a little talk he seems be able to calm me because hes my angel and has so much faith in me. He just always knows Im going to be fine and Im going to get better. Then I was happy again and smiling and talking to the family like nothing had happened at all. About an hour later my daughter comes in she is 15 and she started in on me not doing something for her that I was supposed to do and my switch flipped again. I felt like the whole world crashed down on me. It turned into a large screaming argument and some very hurtful nasty things were said going both ways. I ended up almost moving out and leaving my family again that day. If my husband hadnt stopped me and told me that this was not the end of our family it was just a disagreement it would be ok everyone just needed to calm down and that things should have been handled differently. To me it did feel like the end of the world I was planning crashing my car into the river in the middle of the night so no one would find me until it was to late, all over a argument. This was one of the worst days of my life. I have had many more like this too. I hate cycling that way so many times in a day.

Its not something I do all the time though. I usually cycle from being hypomanic for a week or two to a small depression for a couple days then back up throughout the spring and summer months. Then when the clocks get rolled back and the days get shorter I start to cycle slower and the hypomania slowly disappears and depression sets in for a long time until winter is over. I do have these days you talk about though many many times in the spring summer fall. Never winter thats mainly just depression. I think we all cycle differently. I have never really been stable so I dont know exactly what that is. I guess for me my stable is when im just hypo with small slight depressions like a couple days long and then back up. That would be when I feel at my best. Im talking about not going into full blown mania, not having any delusions or spouts of psychosis or any deep dark depressions.

Hope that helps you out some.
