there is a spiritual “ailment” called I think anomie, I will look it up when I can turn on the lights, which is what you describe, sloth and not caring about it at all.
Tools Matter, and Thoughts Matter (in the spiritual life) are two books by Margaret Funk OSB which describe this condition (and other dangerous times in spiritual life) and how to combat them. in fact, this is one of the dangerous “thoughts” she mentions.
her advice is classic Catholic spiritual direction and very helpful, in fact, I would rank these as two necessary books for any Catholic trying to grow spiritually.
She makes the point to first deal with anything in the rest of your life that is damaging you–physical, mental etc. If you have symptoms of depression, for instance, or of physical problems like diabetes, that could be contributing, seek medical help immediately.
more classic spiritual direction, from rules of discernment by St. Ignatius and others, never make drastic changes in your prayer life, work life, vocation, career, purchasing, circumstances (where you life etc). when you are in this state of mind.
This is exactly when many people leave the priesthood, leave the Church, get a divorce, quit jobs, quit school, change majors, move across the country etc., and it is exactly the wrong thing to do, because you simply cannot make rational decisions in this frame of mind.
above all remain faithful to your prayer and sacramental life, it is vital to your spiritual, mental, emotional and even physical health, and it is your lifeline. do exactly what you have done, ask others to pray for you when you can’t pray.
It may help you and others to know that there is an army of people praying for you: older folks like MIL who prays in one way or another all day, and sometimes all night long, for those in her family and around the world who need prayer and cannot or will not pray for themselves. It includes shut-ins, nursing home patients, even Alzheimer patients, those undergoing severe medical trials, those who can’t do anything to help themselves or others, so offer up their sufferings as silent prayers. These are very powerful, and this intercession is in your behalf.
