If I were you I should not worry with de Caussade and his ilk. Most books of that sort are written by and for religious (monks and nuns), and once they have made a clean break from their family and the world, they have not got the same kind of troubles that we have. It is much easier to be "abandoned" when you are not tied up and twisted and rooted into those you love; and if you are a married woman with a family, you must love your family and you must mind what happens, and whether you can pay the rent, and whether there is anything in the larder, and so on. Your sanctity comes from putting your trust in God for yourself and your family, and you are not expected (by God) to be indifferent to those whom He has given to you to be loved by you! If you try to apply (as many do) ideas which even in a monastery are difficult to practice, to life in the world, it will end in depression.
It's not wrong to worry or fear, but it is wrong not to accept worry and fear if they are your personal cross. Only hand out the worry and fear to Our Lord; ask Him to bear it with you.
--Caryll Houselander, Letters
Jean Pierre de Caussade, in case you are not aware of him, was an 18th century French Jesuit who for a time was spiritual director to a congregation of nuns, and wrote (for them, I assume) Abandonment to Divine Providence.
