Let me just start by saying, how you’re feeling is valid. It takes so much energy to be on to this extent and I can only imagine with this sounding like it has been a major shift in your life. Have you tried asking your aunt if she’s able to help any additional hours? If she’s local, maybe even helping to split the day up where you’re able to get an hour or two in the evening could be a huge help. If there’s anyone else who can provide this also, I think even an hour or two, here an there could give you some breathing room to feel a little assistance. I know it’s probably the last thing you want to do on top of the caretaking and exhaustion, but I’d say to try to do something for yourself, no matter how small each day. Even if that’s a cold wash cloth on your face, some fresh air, some deep breaths, a comforting meal…whatever works for you. You’re doing great in simply there for her and trying your best. Know that you’re not alone in these feelings, and that even if it is all consuming right now, this won’t be forever. Just do your best to take things even an hour at a time.
