Then I recon we have found your problem.At the bottom there is a picture of where Trevor Immelman stands, look at his positioning.
Just look at the position of his hands and try and replicate that rough position.
I would also recommend starting with the club shaft at a forty-five degree angle and find out where the ball meets the club face. If the ball hits the heel of the club, you are too close to the ball, if it hits the toe of the club you are probably too far away.
Another important thing is to find a way to key your distance so that you stand the same way every time. Some experts recommend grip your club with your top hand, with your club touching the ground behind the ball, and extending your fingers out to touch the same spot on your body each time as you take your stance.
I also think the picture at the bottom with the two golfers could also help.
You can practise just getting the position right in your living room, stand by a mirror or film yourself. How far you stand away from the ball is hugely important to your game, get this right and alot of your problems might be solved.
Good luck.
