    Reaching out to others

    Living with myelofibrosis may be particularly stressful for patients. They might not know how to talk about it, and it may be hard to know exactly what kind of emotional support they need.


    • Be realistic about what you can do, and learn how to pass on the responsibilities to others if necessary
    • Tell people how they can help
    • Work with friends and family to make a plan of what needs to get done
    • Let go of tasks that can wait until later because you can always go back to them at another time
