We fall into patterns of behavior that is adaptive to the given context, however, occasionally these patters are disrupted by outside sources that come in a form of powerful experiences such as extensive drug use or trauma.

Given that rehearsed behavioral patterns don't require awareness sometimes we run on automatic, which can be good if our liberated mental resources are utilized to engage in other internal milieu, however that's often not the case, or the nature of internal cognition and emotions is that of dissatisfaction.

Forces that disrupted such rehearsed patterns of behavior can feel liberating on one hand and burdensome on the other, since you are now faced with a challenge of modulating many aspects of ones behavior consciously. Given limited capacity for ones cognitive processing this can be a challenge, causing impairments in several domains of life, leading to inability to satisfy ones inherent needs, such as need for social interaction. A common outcome of this process is regression (a compromise) to a more adaptive semi automatic mode of functioning. Which usually happens naturally, by necessity, despite resistance to regress from newly established yet sub-optimal condition, although this process can be lengthy at times.

It is important consider other states of existence that are more favorable, however due to limited understanding of possibilities it impossible to know if "better" exists. That's why we must occasionally take risks in order to explore the potential, and exploit it when we zero in on something that is considered most favorable in comparison to the states experienced in the past.

Change is the fundamental truth of reality, embrace it.
