Obsessive thoughts can interrupt your daily life, upsetting you and making it hard to do things you want to do. Even if you’re aware they aren’t real and know you won’t act on them, you may still feel distressed and worry you could act on them. As a result, you might try to avoid everything that triggers these thoughts.

Compulsions refer to mental or physical responses or behaviors to obsessions. You may feel the need to repeat these behaviors over and over even though you don’t actually want to be doing them. This can take up hours of your day.

Carrying out these compulsions brings about a sense of relief from an obsession, but this feeling is usually short-lived.

Sometimes compulsions are related and relevant to an obsession. For example, you might check, unlock, and relock your front door seven times before leaving to prevent a break-in.

But in other cases, they might be totally unrelated. For example, you might tap a specific area of a wall before leaving the house because you feel it helps to prevent getting in a car accident on your way to work.
