Welc
me Kevin!
Sorry to read about your accident. About the best thing I can suggest is that you try out some of Kirk's easier lessons, but when you attempt it just try it one bar at a time or better still, practise the first few notes over and over until it is familiar with you. Then move on to the next set of notes.
Hope that is helpful to you. If not, I'm sure someone else will come along and offer more advice that will benefit you.
Hang in there!
