There are at least two causes of anxiety: conflict and stress. As an example of the former, we can rarely predict the precise consequences of what we do, but we are awarded (or cursed) with the intellectual capacity to anticipate the advantages and disadvantages which may arise for any action we may be contemplating. Very commonly we are faced with a choice between several courses of action, all of which we have reasons for or against. This state of affairs — in psychological jargon, multiple approach-avoidance conflict — accounts for a great deal of our worrying: worrying, that is, about what to do.
The other major source of worry is the dreadful things which may happen or have happened to us or to those we care for. Among the most stressful of these are death, illness, loss of work, money problems, marital problems and retirement. Such worries have a rational basis, but we are curiously irrational in the way we pursue them. For example, fear of death is as strong among young adults as among the elderly and it does not seem to be reduced by any sort of religious faith, including the belief that there is life after death.
