There is one question I’ve asked myself ever since I was diagnosed as “bipolar”. I use the term “manic depressive” myself. It is a more accurate label for what I have. The question is “can this high last forever. i.e., last as long as I’m still alive?
There is no answer to the question because you can’t prove what may happen in the future. But experience tells me it’s very, very rare for mania not to lead to depression.
The longest any mania has lasted for me is 9 to 12 months, usually followed by a multi-year (3 to 5) depression. This time you can guess I’m hoping this mania/hypo-mania lasts forever.
So the answer for practical purposes is no, but my high flying mania thinks the answer is I hope so…
