Make a migraine action plan that your family can be a part of. For example, list household duties that you need help with when you're dealing with a headache and assign a person to do each. Let your family know that certain signals, such as lying in bed with the shades drawn, mean that you can't come down for dinner or even talk, and that they should make plans without you.
When you have a migraine, you can feel quite debilitated. But when you're feeling good, you're likely quite productive. If friends or family are overly helpful or offer unsolicited advice, tell them that you've got a treatment plan worked out with your doctor. It's good to have help, but when people do too much, it can make you feel less capable.
Most important, be flexible and positive. Migraines may sideline you from time to time, but be sure to schedule a full social and family life for the times you are headache-free.
