These questions may be kinda vague, but I hope someone well versed in typology can give me some answers. Can a very difficult and stressful childhood coupled with a response of emotional suppression and any other number of environmental and internal factors actually mold one into a different type (such as a thinker instead of a feeler, or I instead of E)? If so, does that mean that what we were before is still our most "natural" way of functioning, our true type, or are we forever changed? This is assuming that we start out very very early in life with a definite type preference. I guess I'm wondering, if one is forced to carry extreme burdens in the stage of life when we are rapidly developing our personalities and developing our sense of self, how much of an effect can that have on transforming our personalities, and is there any going back?
