They aren't ever going to find the happiness they're looking for. Until they address their impulse issues they will forever be unhappy in their own skin. Every glimpse in the mirror is a reflection of the fact that they lack selfcontrol. Every shopping trip is a stark reminder of their addiction to the dopamine hit they get when they indulge in treats or excess food. They can't stop because they refuse to see the underlying cause, so they will continue to push everyone else to accept them and for themselves to love themselves at the same time. All of it fruitless, forever.
