Its called calculus.
How do i stop being so worried about stalemate while being a queen up and opponent's king is naked ?

okay

I don't think it's possible to stalemate the K in a K+Q v K ending unless the weaker side's King is on the edge of the board - so you shouldn't need to start worrying until you've driven the King to the edge. Then you just need to double check before you make your move that he'll have a square to go to if you're not giving check.

Dont worry dear friend. As you improve you will not even think about checking for stalemate, your powerful mind will check it automatically. Its just like passing someone that is going 10 miles per hour on the left lane, you flip them when you pass them without thinking.
I am not saying this is the best method, or the fastest. Its just something easy to remember.
thank you sir this works like a charm
Give the King a robe, at least let him die with dignity!
he he it took me a little while to understand joke but lol :')

he he he :') awesome analogy
You do things a little complicated. When I was a beginner I had the same problem. The solution was easy.
Treat the queen like it is a rook.
What's the basic mating position with th rook?
In all cases the enemy king has to be on an edge file or rank and your king opposite.
Now let's see the basic stalemate position with the queen
The enemy king on the corner and the queen in either of the 2 squares that form a knight move(if you replace the king with a knight , then the 2 squares the "ghost knight" could move are the stalemate squares). This is what you need to avoid.
So here is what to do , the easy way.
thank you for the vast knowledge and also thank you for showing some stalemate position and to avoid them

Practice mating with a rook. The final step for a queen chekmate can be like a rook mate you just have to make sure when you move your queen to give only one file or rank to the king that he has at least 2 squares.
Beesides calculating that you aren't stalemating your opponent, which is rather easy, you could always ensure that all your moves are check. That way there is no fear of any stale#.
yes i have practiced endgames against computer, but still i have fear all the time while playing against my opponent . is there any rule i am missing in stalemate ?like i didn't know the blind spot of knights which is 2 squares in diagonal to your piece btw if you don't know(https://www.youtube.com/watch?v=09Pt_MHgqY4) . is there any rule i am missing to avoid stalemate.
you can see from step 57 how hesitant i am about stalemate
