PRAYER AND OBSESSIVE COMPULSIVE DISORDER
A person with OCD feels good if they carry out a ritual such as washing hands ten times an hour or whatever. They feel bad things will happen if they fail to do the ritual. People devoted to prayer show the same signs. They have an OCD. Prayer is a more dangerous OCD for it is more easily disguised as not being an OCD than the handwashing is. The person with OCD knows that the ritual cannot work but feels compelled to act as if it does. Thus it is the same as prayer - prayer in some people is a symptom of OCD. Christianity insists on prayer without ceasing - you even offer up your actions as prayer. Thus that religion is trying to make its victims suffer from OCD.
Psychologists only see an OCD where some habit affects the person's daily life in an unreasonably harmful way. But that criteria is too external. It is what is inside that is the problem.
Prayer is to reflect the teaching of Christ that God is to be loved with all and not most of your being. Yourself and your neighbour are to get less love. In fact to love yourself and your neighbour to please God is not loving them at all but loving him only. Prayer strives to create extreme OCD.
