Even with physical health, which is up to Hashem, one must do what he can naturally. So, for sure, in spiritual matters, which are totally up to the person, it is up to you to help yourself. Hashem demands and gives everyone the power to be successful. Use the mikvah, say Chitas, and give tzedaka before Shacharis.
