There will be bad days
Mood changes and depression often come with fibromyalgia. Both may also mean that some events need to be canceled, and family gatherings might have to be missed. With this, do not be angry and just be calm. Forcing your loved one will only create more issues than down the road, and often, things can be rescheduled. Approach these kinds of situations realistically and keep as open as a mind as you can.
