I am not happy with my position in family, it feels like i am the lone looser born. what do i do?

its just that i am low confident, nevr upto their expectations, failed at everything , failed my promises, failed my parents...

I was the black sheep in my family. I sympathize because I know how it feels to be an outsider in one's family. But, over time and once I got older, I decided who was a part of my family and what family meant to me. It is going to hurt not to feel accepted or not treated in the way you would like. But maybe you feel like a loser because you are not living the life you would like, and maybe your family does love you very much. This is your life and you need to work on becoming the man you want to be.

Make some self improvement... Take sine classes better yourself.

Be successful and make them look up to you.
