When you are becoming a new and better version of yourself, manifestations from your old self will pop up. Don´t entertain them! See them as travelers on a layover, who are not planning to stay. Don´t make them stay!
The only reason they will persist and keep showing up in your reality is when you serve them coffee/tea and give them more attention than they deserve. Just say “Thanks for reminding me that I am no longer that old version of me” and focus back on your desire- live in your end. All of that will fade away.
Whatever shows up in your world is only important when you make it important!
Understand that your thinking- good or bad- is always responsible for the results in your outer world.
