I think we all reach at some point that stage of life where you find yourself now, where we seek to unlearn so many things. From personal experience I know that unlearning is not entirely easy, but it is possible. And regarding what you said about how not everything we learn heals us; sometimes I would even say that some things we learn can hurt us, if we don't limit them or manage them well enough at an emotional level. Anyway, this is my opinion on the matter.
