Years back, I'm afraid I can't find the study anymore, it was determined that people trying to build new habits would often fall back to old behaviors when exposed to situations that caused them produce adrenaline (fear) and cortisol (stress) together. So, in today's world, i think it's pretty safe to say we're all facing an uphill battle when trying to change, regardless of our individual challenges. But, no, I don't think it's hopeless; It's about understanding that you're a little fish in a big ocean and sometimes the currents are going to pull you in a direction you don't want to go and you've basically gotta find a story to tell yourself that works for you to help stay focused on where you want to go.
