I have confidence in myself but when I view myself externally e.g. videos, I find the way I behave and my facial expressions very awkward.

On the inside I feel assertive and I'm not bothered by the fact that I have a resting bitch face, but from the outside, my movements are weird (long af limbs), my smile is unsettling and I cringe at myself.

Actually seeing myself depletes my self-esteem. I don't wanna pretend that's not happening, cause that's genuinely how others see me, and it's very different to what I perceive of myself.

How do?
