I was diagnosed with MS in 2002 and Fibromyalgia in 2011. Many symptoms are shared by both diseases. Regardless of the name of a condition, you need to learn how to live with it and to stop it from drowning your creativity. This is no easy task. I strive to prevent my condition from having total control of my life and my creativity.
1. Start small
Do not expect that you can work on your craft for 8 hours a day. Some days, you may be lucky to work for 2-3 hours and you need to be content with that.
2. Limit your expectations
Planning ahead with these illnesses must be allowed to have backup plans. If today is not possible, than tomorrow may be what you are aiming for. Do not chastise yourself for not achieving your short-term goals. But at the same time, DO NOT QUIT!
