i forgot I always have trouble sleeping and am constantly exhausted. i think bipolar gets worse as you get old.

Bipolar has been proven to get worse with age, its not a matter of belief its a matter of medical study - all mental illness gets worse with age as our brains age too and mental illness gets worse. Regardless of meds you cannot control BP completely, the meds act as control factors but sometimes and often over time your body adapts and meds need to be tailored.
