Talking with Family
If you're close with your family members, many of them probably already know, or at least have an inkling, about your condition. Since OCD tends to run in families, you may have a parent, sibling, or other relative who also exhibits OC behaviors. If this is the case, you — and your OC family member — may find in each other a ready source of support and information.
One thing to keep in mind is that family members will be more likely than others to worry about your health and show concern for your well-being — perhaps even exhibiting some protective tendencies. Try not to take offense; this behavior is undoubtedly driven by love and care for you. Still, you may need to establish some boundaries. If your mom calls every day to see how your treatment is going, for instance, that will probably only contribute to your anxiety. Set guidelines for yourself and your family.
One reason to consider telling your family that you have OCD is that it runs in families. Other family members may have it and not realize this. While you can't diagnose others based on your experiences, you can, perhaps, set them on a helpful path.
Also keep in mind that some family members will have the opposite reaction and either start treating you in a negative way or avoid interaction with you. OC behaviors may make people uncomfortable. More likely, relatives may wonder why you've only recently started behaving in ways they don't understand. They might think you're trying to be difficult or different, or get attention for the sake of it. The best thing to do in this situation is to try to educate the person in small doses. (You'll read more later about some ways to do this.)
