You are welcome, chocmouse.

Event if you aren't actively pushing yourself, do thoughts sometimes arise along the lines, "I would love to be able to do such-and-such"? If you feel ill (are you homebound because you are ill?) thoughts like that could feel oppressive.

Or perhaps that's not the right way to look at it.

It might be simpler to say that you feel you are drowning in the struggles of your day-to-day existence.
