do u feel jealous of ur siblings

I would have to admit that I'm jealous of my younger sister sometimes because my family loves her boyfriend and it seems that she can't do anything wrong but the person I'm with and the things I do in life are never good enough. I had a kid - mistake in their mind and it was at first, but now I love him more than anything. His father they will never like. I'm just screwing up my life, I guess, and my sister can't do wrong.
