Hello @twopoles1 and welcome. It sounds as though you're newly diagnosed which takes adjusting. Then there's new meds and all.
For me yes I experience that. I think there's two components. One is that it's part of the cycle. The other is that antipsychotics (if that's one of your meds) can have an impact too so many psychiatrists try to "titrate" the dose down to a low but still effective amount for maintenance, while being open to revising it upwards when needed.
Something to be aware of is many psychiatrists try to avoid prescribing antidepressants to people with bipolar as they can tip you into mania. But my psychiatrist has suggested there's a mood stabiliser that might help.
Selfcare and maintaining connections is very important during a depressive phase. Some people call it having a toolbox of coping skills. There are forum threads to help with that.
Enjoy your Friday... any plans?
