Your problem is a common one: You simply don't pay any attention to your opponent's moves. He makes a threat and you ignore it and lose material, over and over. You have to look at your opponent's move and check to see if he is threatening something, or if he has overlooked something and you can win material. But look at his threats first!

don't worry about elo loss. you'll regain it easily. just learn the basics, play more and enjoy the game. you'll improve eventually

Go to lessons, analyse games and keep your spirit up!😊👍

I have looked at a number of your games. They are a mishmash of dropped pieces, missed checkmates, random-looking moves that threaten nothing... Your rating should not be your concern. Fix the problems of planning, attacking and defending and your rating will go up. Ratings only reflect performance and performance is generally based on skill level.
