We are all delusional.
This idea is what keeps coming up for me.
How do you see the world around you? Your imagination might be playing, and we make up things in our minds. You question whether this thing is a reality or not.
You may think you are being delusional but, in most cases, you are not. The best part of being delusional is having two options: being delusional in your own suffering or learning how to live and carry your grief.
