There will be those that, no matter what you do or say, will actively choose to remain mired in their negativity. They have been in that particular space for so long, they know nothing else and no amount of cajoling will make them see your world otherwise. It is their safe space and they will steadfastly refuse to abandon it. The world and all its inhabitants have done them wrong and, by God, they will make sure you know it!
As challenging as it is, let them be. If they have chosen to expend all their time and energy wrapped in their ‘security blanket’ of negative energy, it is their choice! Continue to send them Unconditional Love and rest assured, dear one, you have done what you could. Let The Universe handle the rest. ~ Creator
