I make an F just like Slipin shows in his first "version". Maybe try this, make an open E chord using you 2nd, 3rd, and 4th fingers. Once you can make a clean E, slide all you fingers up one fret and get your first finger to cover the a and b stings. It may help if you move the angle your hand is to the neck, move enough your elbow is moving. Clip your nails short they get in the way. Learn it right, it's worth fighting for.
