Sorry to hear that. I’ve also been living with chronic illness for the past 4 years. So far the given diagnostic is fibromyalgia. For me playing with others helps me forget my pain better.
Don’t despair though, once medications settle in and you find a good food habit it will be more manageable. You will have harder times but they won’t last.
Don’t hesitate to speak with your doctor if you find you don’t have energy and will to do your routine, it’s normal to go through that with chronic illness.
