Yes our upbringing does set the template of how we believe, think and live.  It is a challenge, a struggle to break those patterns and reprogram our neural pathways to change to other ways of living/thinking/believing.

Step-by-step, living consciously and mindfully and lovingly to change dear Cat.  You don’t have to do it all at once right now.

It sounds like your living situation is not healthy.  Getting good sleep is the foundation for health.  Your roommate is preventing you from that first step of good health and changing your life for the better.
