please, how do i fix low self esteem?

having an epiphany i am my biggest critic and it's killing me that i can't even accept compliments, my immediate reaction is to deny and move on

It will take time, but you have to start accepting compliments by saying thank you. You can accept their opinion but it doesn’t have to be your own.

You can also write some positive things about yourself and put it on a bathroom mirror.

Practically (and from my psychology degree) you have to learn how to be less hard and more appreciative of yourself. You may be experiencing some cognitive distortions about yourself. See this list:

they/them, candlemaker at 🕯️humankind🕯️, seemore.tv/humankind, hosting /samantha and /humankind

Instead, challenge negative distortions about yourself. Writing down example thoughts and reframed thoughts can be helpful.

I am open to hopping on a call with you to help you work through some of these (although I am not a licensed therapist).
