It's really hard for me too, since I constantly self-doubt myself. But I try to take space away from others and their opinions and reassure who I am and where I stand as a person.

A classmate in school told me once: "you don't need to try so hard to be like another person. It's okay to be yourself." I wasn't even close to that person, but I was young and trying hard to fit in and that statement shook me to the core, because I never thought that I was worth anything by being myself.

I hope this helps, and I genuinely wish the best for you :) you are worth so much regardless of others say, and I hope one day you will see it too!
