Hello Kakie and thank you for asking this important question regarding adult learning. Yes, there is extra help for adults who have difficulty focusing.
I would start by reading the section of the CHADD website I have listed below. CHADD is an organization that helps people with Attention Deficit Disorder (including adults) by providing information, support networks (on-line and area meetings) and current research information. It is possible that you may have an attending disorder. However, only medical personnel should determine if this is indeed the case which is why you should consult with your doctor.
If you do have an attending disorder then professionals can help guide you as to the correct treatment and support for you. Adult attending disorders are no uncommon. You can succeed and I commend you for furthering your education as an adult student!
