Sounds like you have a huge amount of help response here on this list. When you said you had some problems with being able to follow directions due to a med you must take it rang loud and clear to me. I have a grown daughter who has been on meds that gave her similar issues. Her glitches are more with verbal directions so writing things down for her is helpful to her. I would say we are still learning ways to do a work around when she hits a glitch. I bet you will do well with demonstrations for the quilting information you want to learn. Things she has done hands on stick with her better than things she hears or reads only. Let people know you have a glitch and what would help, then they will rise to the occasion to help you in a way that works best for you.
I'm sorry your local shops weren't more responsive. Keep reaching out for quilters that just enjoy sharing our favorite hobby and ongoing learning. I'd be happy to help you in any way I can.
