Once you’re stable, do you ever have to keep swapping meds?

I’m 22, so my brain is just about done developing, but I was diagnosed at 9. When you’re so young, your hormones keep changing and making you have to swap meds over and over and over again.

I just want to ask other adults here if that kind of continues into adulthood as well. When my next episode comes, will I have to swap again? Are we supposed to swap meds after every single episode?

I should know this stuff after having it for so long, but I don’t talk to too many other bipolar folk, and lack a lot of knowledge we need.
