Help me.

If that was my case, I'd try to analyse what is going wrong in my games (the opening, queen blunders, missing mates, etc.) and try to solve it. Also, I wouldn't recommend resigning at a beginner level because there are other solutions: you can play for time OR play for a draw (by agreement, repetition or stalemate). I've saved myself so many times for avoiding the resign button. Also, good luck on your journey! :D

You lose because you made the last mistake.
Always blunder check before you move.

I checked some of your games, and I think you are resigning way too early. Try to set up traps and and always check if something is protected or not. Try to think what your opponent is trying to do and plan accordingly. Even when you blunder, don't resign and try to trick your opponent.
