How can i raise up my self esteem and be more confident about myself?

Effort: Trying things you are good at wil help boost your confidence. Doing your best in the things you feel inadequate should be your goal rather than been overtly concerned about comparing your self to others. As you continue to improve and socialise you will start to notice your self cinfidence improve. Good luck young man.

Self esteem: Do something everyday and it build self confidence. Every body can do something to help others all the time.
