What would mean this needs more than a course

These are here in lesson one rather than at the end, because somebody in a bad enough state may never reach lesson six.

Rituals that now take real time. Wudu repeated, prayers repeated, the shahadah repeated, a verse recited again and again until it feels right. Prayer being avoided altogether because it is where the thought lives, or taking hours. Distress high enough that work, study or sleep have gone. Confession behaviour that is escalating and is damaging your relationships.

And three that go faster than the rest. Any thought of ending your life, particularly with a settled belief that you are damned and that it is already decided, which is a combination that does present in exactly this pattern. A belief that you have committed something unforgivable by having a thought. And doubt that arrived suddenly, out of character, alongside other changes, or alongside hearing voices or fixed unusual beliefs, which needs a medical assessment rather than a course.

If one of those is yours, lesson six has the routes, and there is no reason to read the four lessons in between first.
