It sounds like you love music and have talent - if so, guitar is just a matter of time. The trick with guitar is to get through the first stage where your fingers hurt and you don't sound good. As soon as you can strum to a rhythm and change between about 4 chords - you will be able to play songs and it will start to feel more like "fun" than "practice", even though you will continue to improve from there. I call it "getting over the hump"!

For me the main thing that people don't talk enough about when teaching guitar is keeping the rhythm with your body... I tap my foot and then both hands must follow that rhythm together.
