Left handed grip, right handed clubs

Yes, thats correct. I cannot play at all the other way, Ive tried and Ive had lessons but I just cant hit the ball. However, the way I do play I'm averaging 12 to 14 over par, depending the course. I know I can play better and get an official handicap, I just dont have the time to play regular at the moment due to work. The reason I ask is because I read a lot about golf in the hope of improving aspects of my game and there are a lot of references to grip, but I dont hold the club normally and wondered if there are any tips out there.
