i appreciate that it sounds like you're in a stressful situation in terms of your family's cash flow.

is it possible to switch your arrangement with your client to daily billing? in a way that doesn't leave you worse off financially, compared to what your average daily revenue is currently based on hourly billing. i dont have experience with pitching this to people who had previously agreed an hourly rate, but some of the other folks here might have suggestions for how to frame such a conversation so it comes across as a win for your client as well (focus on the output of your work rather than measuring your time inputs, maybe?).

if you can do so, it might make it easier for you to justify timeboxing some time every day for self-care and non work stuff rather than feeling the need to bill hours, and help you produce better work in the long run.
