OCD sufferers will look for reassurance: it temporarily reduces their anxiety and so it is only natural that they will seek it, however reassurance only makes things worse because it feeds the cycle. Even though it will feel harsh, don’t give out reassurance, as it won’t help them get better. A ‘tough love’ approach is often what’s needed.
Common examples of an OCD sufferer seeking reassurance could be asking a loved one to help them complete checks or compulsions such as ensuring the doors are locked multiple times, or if their fears centre around harm or sexual orientation they may want to be reassured that they have nothing to worry about and that that they are a good person. It’s extremely tempting to give in and go down this road but it only serves to make things worse in the long run. A good strategy is to learn more about OCD yourself so that you know how to handle these situations, it isn’t easy being a loved one of someone with OCD and it takes persistence and patience to help them on their road to recovery. Ultimately it is a path they have to walk for themselves, but having a supportive network is of course beneficial so your understanding of OCD will be sure to help them.
