Left handed people live less due to high stress coming from having to use the mouse

I am left handed, but my wife is my right hand, the problem is I use the mouse with my left hand and recently swaped the left click to right click and viceversa due to how good it feels. Sadly, playing league is another story for my left hand because I can't left click anything anymore, examples: Can't click on the minimap to take me where the action is without actually clicking to go there, wanna buy an item in ARAM? Sure let's move your character at the same time and now you can't buy.

How can I "hack" it so my left mouse click, which is now the right click, to work as the right click in the game? P.S: Right mouse click to work as left mouse click.

"u aint gonna hit me if you move backwards lol"
