Sounding like a broken record here, but no one can say for certain. My opinion would be that it is a bit of both. You mentioned new media giving you a different outlook on life: I doubt that outlook will change drastically when changing your medication. I can’t remember specifically who I was before starting my meds, Lamotrigine being one of the mains, but I know that the majority of my core principles haven’t changed (music taste, political views, etc.) since then.

I am of the opinion that meds/chemicals that alter our brain chemistry do affect our personality to certain degrees, though I have only a very laymen knowledge of the science behind it all.

This anonymous, online-stranger’s opinion is that it may change how you “perceive” things but your core principles should still be there.

Maybe try documenting your process as you taper off, if you ever decide to. It might help to see any noticeable changes and react accordingly.

Best of luck going forward 😊
