My father died on January 2nd. I was busy with arrangements and visiting with relatives who came to the funeral for the next week and a half. My mood stayed uh. Not good, not bad. Now in the last week I have become depressed....sad, think about self-injury and suicide sometimes, no energy, isolating, nothing is interesting, flat affect (couple of people told me)....now I wait for ECT scheduled next Wednesday. I don't want to change my meds.

As to your question, there is no regular schedule for episodes of mania, hypomania or depression. You could be stable for a long time and then suddenly have episodes of depression and mania, then stable again. No one knows when an episode will come.
