That is helpful. Thanks ! :)

Meditation/mindfulness and good sleep hygiene worked wonders for me too. As a grad student, I also suffered with anxiety due to imposter syndrome. Here is my shift in perception that helped me.

Stop taking yourself too seriously. Listen to the stories you tell yourself about you. When your mind tells you that you don't know anything, or how come you didn't achieve anything "significant" if you are so talented. Will you ever say this to your friend? Or to a child? Your relationship with yourself should never be worse than what you have with an acquaintance because you don't really know yourself. I was constantly surprised by myself when I started inspecting myself.

Start taking yourself just as a streched-out child. Life is too short anyways. Find the innocence that is there in you. No matter how many times you fail or succeed, you still love you.
