They aren't beating you because they bring the Queen out early; they are beating you because they are catching you flatfooted.
At your level, studying basic tactics: pins, forks, skewers, double attacks, overloads (and combinations of these simple elements) will do a lot to improve your game.
Add to that some familiarity with typical mating patterns (Model Mates) and a bit of endgame study, and you could probably strengthen your play by four or five hundred points.
I am just learning (700-800). When I play better players the advise I get is not to move the Queen out early. However, I lose several games by my opponent moving thw Queen out early and catching me flatfooted. Suggestions appreciated.
