when tu lose at something ,you lose your self-esteem ,how can tu back it again?

The most important thing is being able to tell yourself tu did your best. tu can find ways to improve if tu want.
The problem with comparing yourself is there will always be someone better. But, tu can always strive to be the best version of yourself.

Good question.

When my folks realize I'm down about my esteem o whatever, they know what to talk about.
