Sometimes walking away has nothing to do with weakness and everything to do with strength. We walk away not because we want others to realize our worth and value but because we finally realize our own.
Oh my yes, but did I learn, and learn well. Thankful for those long past mistakes that taught me!
Detach from the things that bother you so much... you nearly slip into your less than your best self. Don't get caught up in the negative. Deep breath. Don't let stuff bother you. Don't let it in. You're happier than you've ever been. Walk away from anything that tries to take that away. Grace and dignity. Maintain that mindset.
