Don't stress so much bro, you will improve in due time. Progress is never linear, the work you put in may not show results now, but i assure you its not being wasted. Everybody plateus, just remember that at the end of that long road, you will be rewarded. Meanwhile, have some fun in your games and loosen up. Here's a passage from the book 'Atomic Habits' to alleviate your stress ;

lmagine that you have an ice cube sitting on the table in front of you. The room is cold and you can see your breath. It is currently twenty-five degrees (Fahrenheit) . Ever so slowly, the room begins to heat up.

Twenty-six degrees

Twenty-seven

Twenty-eight    The ice cube is still sitting on the table in front of you.

Twenty-nine degrees.

Thirty.

Thirty-one

Still, nothing has happened.

Then, thirty-two degrees. The ice begins to melt. A one-degree shift, seemingly no different from the temperature increases before it, has unlocked a huge change. Breakthrough moments are often the result of many previous actions, which build up the potential required to unleash a major change.
