A great deal of how we go through life is from what we learn. Anything learned can be unlearned or changed to better "fit" our life and what we really want. Medicine does not cure anything, it just helps with symptoms and makes some things easier and maybe assists the body in doing its work (and maybe not). Only one's body can cure itself, the chemistry and balance is too complicated for humans yet, messing with it. You take one pill and it has side effects that you take another pill for, that sort of thing. Sometimes you have to take that pill to save your life (antidepressant side effects beat committing suicide, for example; I had to take too many antibiotics to get rid of an infection that was threatening my life that the doctor's didn't understand (hence the too many, they were the "wrong" kind, I needed 2 different ones but the one kept me in the fight until we thought of the other) and now I have other problems as a result.

Our body knows what it is doing. So sometimes it's just a matter of helping it by learning/unlearning things that are making it hard for it, getting in our way mentally. Therapies like CBT/DBT can help there or there are lots of other things to try, it's an individual thing what will work for one person as one's mental health is individual. I'm not depressed, perhaps you are not anxious, etc.
