piece of my mind/peace of mind

there's a scary similarity between the sentence structure but the two states of mind are screaming lightyears apart
(remo image only here for the "piece of (my) mind" reference)
while i've been in therapy for years (and it's given me a world of difference) there are some bits that refuse to shift, habits that are too forceful
act mindfully
all about embracing your demons / acceptance & commitment therapy
what are my demons?
*eating mindlessly distractedly desperately for comfort
*buying mindlessly distractedly desperately for comfort

*ignoring friends, allowing myself to drift from contact
*hiding from life burrowing & hibernating, and allowing myself to think it is too difficult to face
*ignoring my physical body's needs -diabetes & weight issues especially blood sugar control, exercise, good food
