How do you get out of a depressive state when dealing with ROCD?

The ocd/depression see saw can feel really awful and disheartening. One evidence based treatment/intervention for depression is behavioral activation. This involves in a slow and challenging way, engaging with routine activities, valued activities, and enjoyable activities that you've reduced or stopped doing. Long story short, try to make small but manageable goals to still be engaging in these things even when (or especially when) it feels hard. Good luck!
