Me too!
I can write with either hand although each looks different so I have make a conscious decision to stick with one for banking/legal purposes.
I catch with my left, eat with my left, and punch/slap with my left but throw with my right. I confuse myself with a tennis racket and often throw the racket from hand to hand depending on what my opponent does. Ditto with a paintbrush. I can only knit left handed.
My doctor told me this is why I’m clumsy. I have to think too much!
I know exactly how you feel! If I write on a blackboard or a whiteboard I can write with my right hand since I make the letters larger. I haven’t mastered using my right hand with a pen but if I worked at it I probably could. My main confusion comes if I’m driving somewhere I’ve never been and the GPS says turn left or right. That doesn’t work for me in heavy traffic at times. Sometimes I have to go past the turning point and come back. LOL
