My hands don't do what i tell em to

I play a lot of games that require good hand and eye coordination and my hands are just bleh. They get so jumbled and don't do the right thing!! And I might even have developing carpel tunnel from drawing on my laptop some time ago! My eyes can see where everything is and where it's supposed to go (sometimes. I'm so blind) but my hands never listen. Even on games where I don't need to do all that, my hand still fails me! Stupid hand. They should've never taught me how to write with my right hand, now I'm retarded.
