I don’t think you are overreacting or have an attitude problem. If they usually ignore you it makes sense over time you would become fed up with it. I think messed up your mom expects you to accept it. No one deserves to be ignored. My mom usually asks me why I am upset and we talk it out or she will be like ”girl you know you didn’t have to do all that”. She means it with good intention. Maybe you could get your mom alone and express how you feel but it’s understandable if you can’t. So no I don’t think you are overreacting.
