I've never tried the drums but it took a *lot* of hours for me to get good at guitar.
I'm not one of those instinctual musicians - it takes me a lot of work.
Playing with metronomes can help too.
As long as you're enjoying it? that to me is still my main focus.
I know its a cold winter there - I'm sorry you're down but I'm glad you have a therapist to touch base with Charon.
