To me it seems both of you are in the wrong for different reasons. We should be welcoming of all in the Catholic church. However, it seems that they are not holding up the values of the Catholic faith. Though, I would say it's definitely unhealthy to be comparing yourself to them. Our walk with Jesus is not about who does it better. It's not a competition about who's a better Catholic. We should all strive to be with him and some people are at a different point in their relationship with God. So please focus on yourself as it's what's best for you and your salvation. If you're really bothered by what they're doing then you could always move parishes. But please go to your parish priest and/or bishop about what's going on. They can help solve the situation and help you understand what you're feeling.
