Might I suggest you create an outline of what you expect to be discussed? If you receive an Agenda prior to the meeting, you can pull from that. Leave space after each item on outline so you can write your notes. Of course you would have the "Date" and other repetitive items on top, creating your own template to update prior to each meeting.
I also like what The Skeezyks says "One alternative might be to "job share" with another member so not all of the responsibility falls onto you right off the bat."
I was responsible for the minutes of a non-profit trade association. I always had another person take minutes also, and compare/combine with mine. It was a great help.
Glad things have worked out, and you will improve as you go until minutes become an easy task.
FYI: the word "Save" at the end was not typed by me. Something odd that I don't understand????? I can't delete it..weird.
