Bipolar depression can last for years. Now, I know, bipolar disorder is a cyclical illness – i.e. you cycle through various states like hypomania, mania, depression and euthymia (no symptoms). This is true. But it is also true that a person can get trapped in one of the mood states. This isn’t necessarily the most common manifestation of bipolar disorder, but it does happen. And usually, if you’re trapped in a particular mood state, it’s bipolar depression that lasts for years.
Years of Bipolar Depression
Yes, I’m one of those people who has been in a bipolar depression for years (of various severities). Occasionally, it’s been interrupted by a mixed mood or a hypomania, but those tiny punctuations are dwarfed by the massive bipolar depressions that surround them.
And believe me, in those years of bipolar depression I have tried every medication cocktail known to man. We’ve tried everything there is so we’ve had no choice but to go back to previous medications (and, actually, we’re having some success with that).
