If you want to learn to keybind, I suggest to first quest using nothing but the mouse to move, and nothing but keybinds for actions while killing mobs. Do that for a few weeks until you're comfortable with it, then try it in a dungeon. You can eventually add back some keyboard moving and mouse clicking on certain abilities, but you just need to switch your habits first, and it's less frustrating on a quest mob than when there are other people depending on you.

I'm empty and aching and I don't know why
