Hi,
We are so sorry for you and your little one. In addition to the previous suggestions...Have you considered offering to exchange labor (anything that you are skilled at or are able to do such as running errands, administration work, clean up, etc. think creatively) with a pet sitter or boarding facility (even your vet office)? Just make sure everyone is clear on what and when these exchanges will occur (in writing is best).
Could you create a little safe-haven space in your parent's garage or in an outbuilding/workshop or rentable shed on your parent's property? We would suggest putting up a fenced-in enclosure with an attached top, off of the doorway as well. You wouldn't want her to get out. Make sure the inside is also secure. You could utilize their house as needed but "live" with Kitty in your make-do-for-now space until you get back on your feet again.
Could your friend possibly just allow Kitty to use a single room with a door? Tidy neat and clean with her belongings and a few of yours (for your scent, etc.). You would do all of the interacting and care-feeding litter etc. and your friend would just provide the space and be there as a back-up in case you could not get there.
Have you tried rescues that specialize in cats/or ones that are out of your county?
In the meantime ...Routine. Routine, even less than perfect routine, can foster a sense of security and calm. there are fewer surprises, and things to look forward to-such as seeing you, and mealtime.
We are praying for you both.
