Blame not yourself for another's destruction when you reclaimed yourself from being destroyed. Their response to having reached your limit belongs to them.
Be true to your you when accepting or refusing situations not meant to intrude your life. Stand for your beliefs, have your morals and values announced, heard, and respected. Select who comes in and who must go, who stays far and who stays close. Never place yourself aside or disregard your existence. Do not cave-in when you must show resilience. See, the choices made in your past are easier to forgive once you accept that you did not make mistakes; you were simply setting a limit for yourself with every tough decision you were faced with at that time when you decided enough was enough. Let them gaze at the lines of your back and critique every action, word, or gesture they forced you to pose or pronounce. Their opinion concerning their stepping out of bounds truly does not count.
