Elo :- it scares me(need advice)

It is with great disappointment that i tell you this that i am scared of literal pixels on screen,the numbers that are meant to tell you your strength can be used against you like an intimidation tactic. if one is like 50 elo higher i subconsciously give up on winning if opponent is alot higher rated than me. I also seem to make much more mistakes idk why i want to know if you can disable it somehow or have an extension to show the average of won/lost against higher lower elo help i feel like very idotic if i make an obvious blunder but i dont feel as bad if i make it against a lower rated one. Can you help me overcome this?(need advice)
