This can not be overemphasized in my opinion. The natural result of Atheistic Naturalism is, to me, nihilism and its accompanying depression, so I would encourage an honest examination of your worldview and an openness to faith that provides a sense of purpose.
As it happens, I do believe in God(dess), but what is needed is not religion so much as spirituality -- see https://en.wikipedia.org/wiki/Spirituality
This is a view of atheism which seems predicated on a common theist belief that morality and "purpose" can only exist through belief in a divine being. Yet there are plenty of atheists who are neither nihilistic nor depressed - and plenty of theists who are.
One can believe that life has value, and that life can have a purpose in the context of humanism, and one can even have spirituality without embracing a belief in the supernatural or the divine. As Douglas Adams said, isn't it enough to see that a garden is beautiful without having to believe that there are fairies at the bottom of it too?
Which of course makes no sense because this is not a brand of coffee.
All this to say that such suggestions do not make sense, a belief or lack of is not something which someone can "try out". I can imagine that following some major life events, for someone who is inclined to such a change, "trying out" is an option.
Having had all kind of dramatic events in my life I never felt the need to invoque a superior being. YMMV.
Except for some specific cases, one usually grows with a religion or non-religion and this deeply forges one's perspective.
