It’s only been one day… I’m exhausted

Backstory: my mom had a stroke 8 years ago and moved in with me, she got somewhat better and was able to live independently for the last 2 years in an apartment.

Yesterday she had a fall - broke her arm and two fingers, it’s been 26 hours of caring for her and I’m sooo tired. I go back to work in 3 weeks - I have no idea how I’m going to do this or stay with her and my dog in this apartment.
