Bible Study and brain fog

Although there is much written about "suffering" and on associated topics there seems to be little on how to study the Bible while ill, exhausted and brain fogged. If the illness is of short duration, such as a cold or virus, it is not such an issue, certainly detailed Bible study can be set aside for a little and at most a few Psalms or some of the Gospels read instead. But what is one to do if the illness and exhaustion is long term or even potentially permanent? For it is inadvisable to suspend Bible study indefinitely, right now I am longing to get deeper into the Bible, like I used to before I became so indisposed. Yet I cannot think straight or concentrate and earlier today whilst trying to read the introduction to some study notes on Romans kept dozing off, not because of disinterest, but because of exhaustion.

There is little point deciding to do it later or another day when I am more awake or feeling better, because this time or day never arrives. It simply leads to Bible study being continually put off. So is there any solution to this problem?

The first one that comes to mind is prayer; asking for God's help when reading His word is always essential, but it is not just understanding and insight but also concentration, strength and energy I need to pray for.

Not being too ambitious and studying small amounts at a time can help too. As with anything I do (my memory not being too good) writing things down can help.

I would be grateful for any other suggestions, resources and strategies anyone can suggest. Getting any teaching or study at all can be a real challenge when ill, from the difficulties of making it to church or church group to struggling to focus on or remember anything of sermons I listen to and much else in between. My memory is shot away, memorising Scripture is something I would love to do, and I used to be fairly good on where things were in the Bible, but at times I struggle to remember what day of the week it is, let alone chapter and verse. It can lead to tremendous feelings of inadequacy and the feeling of being a "bad" Christian, especially when even praying is hard and I feel isolated from any kind of fellowship. None of my prayers are ever especially impressive, I don't pray for a long time in one go daily because I'm not really up to it.

Anyhow, input welcome, thank you!
