Second. It may be scrupulosity

If you are not empty but flooded, this is a different thing entirely.

Repeating wudu. Repeating salah. Checking whether something invalidated it. Persistent unwanted thoughts about God or about the religion that you do not want and cannot get rid of. More than an hour a day spent on religious doubt and checking.

That pattern is a recognised presentation of obsessive compulsive disorder, and it is not apostasy and not weak faith. It goes to a clinician who knows OCD. It does not go to more religious study, and more religious study very often makes it worse.

A scholar matters here too, but second, and for a specific job, which is to tell you what is actually required so that it stops being mistaken for a symptom.
