I believe the answer to that is yes and no.

No, if you take care of yourself, make changes in your diet that are helpful and take the least amount of psychotropic medications to remain stable, all the while keeping a close watch on your moods as you are doing now. You will actually mellow with age.

Yes, if you fail to take medications of any type and abuse your body chemically. The brain can rely only on what it gets for food and other
things: rest, exercise, pharmaceutical grade vitamins and minerals--omit
those and you might be on a track for deepening the illness both in
depressive and manic states.

You'll be sooooo--ooooo much better if you become pro-active in your
care, learning what your body needs in the way of vitamin support
to offset the drain that meds cause. (It's a drain on minerals, vitamins,
enzymes and in addition leaves an acid residue--ash--when digested.)
You will need to offset that by supplementing the things lost to keep
good health.
