I'm new to guitar. Chord changes are a bear. Changing from C to G is not easy. Hell, making a C or a G is hard, let alone switch.
But what's helping me is I'm doing finger exercises where I move one finger at a time, while not moving the other fingers at all. Basicly teaching my fingers to move indepent of the others.
I Can now make the chords and slowly switch. At this point that's all I do.
In short, I hope you don't give up music. Try piano? I was told that Piano is easier to start, but much harder down the road.
Anyhow we're all behind you and wish you well.
