A few tips from my favorite spiritual writer and elder Fr. Ilarion Argatu:
On Wed.you generally fast for for troubles like legal troubles, unjust accusations at home or work.
On Fri. fasting is for magic spells,enemies, curses and the forgiveness of sins. For the dead you give the name list to three monasteries, or in cases where the deceased had sinned beyond average, to seven to be payed for at daily liturgies for a year.
You should also know that on Wed. you light seven candles, whereas on Fri. nine are to be lit: three for forgiveness of sins, three for curses and spells and three for your enemies, known and unknown, seen and unseen.
If you are married you will not sleep in the same bed as your spouse when you fast like this, even if you do not come together that night-that before God is an abomination-for the man's body is weaker and still lusts for the woman and so you'll forfeit the benefit of fasting.
Hey, if you're a pious lady with little occupation but church-going, you've got to keep your devotional life in good order, right?
By the way, those candles are supposed to protect you from evil people's spells and curses, not to put spells on them. Even if pious ladies often misunderstand.
If you go to see a (spiritual) doctor and he doesn't at least prescribe a recipe, you'll be under the impression that the whole visit was pointless. People need to be told what to do. The more details, the better. Our Lord himself resorted to things like mud and spittle in some cases.
Holy water, incense, tons of prescribed prayer, long services in almost incomprehensible language, lighting candles and so on clearly have an anxiolytic, benefic effect for people who are in trouble. At the very least, it gives them something to do and some hope, so as not to get stuck/overwhelmed by their problems and feel helpless. Moreover, it's a way of engaging and stimulating one's faith, which alone can do wonders.
I think everybody has their beliefs and rituals, some more rational, others verging on superstition. Suppressing them might not be such a good idea, once one gets into trouble and needs to cope with depression or other psychological illnesses. This is why traditional societies are better at dealing with these issues and can do without psychotropic drugs, expensive therapists and all the psychobabble. Babushkas and yiayias can cure just about anything - trust'em!
