That's discouraging; I don't blame you for being sad, OP.
Had a similar situation. In late August I had to move 250 miles to live with my sister, who has stage 4 breast cancer and had fallen on the stairs, shattering her ankle. She needed surgery, was in a non-weight-bearing cast, etc etc. I was thre for seven weeks, had to make all meals, do all shopping, take care of her pets (one of whom was ill and died when i was there after racking up a four-figure vet bill, which i paid), yard work, cleaning, laundry, etc. in addition to working full time.
As luck would have it we are on deadline with a big project at work so i couldn't slack off or take annual leave. Meanwhile I was paying a house sitter here to check my home, take in the post, feed the birds in the garden, etc. so that was an added expense.
Fortunately I can do my work remotely and was in frequent contact with my team (about 7 people, all peers except for our director, all longtime employees; I'm the longest and also the oldest by at least 15 years; I'm 60).
I got one "give my best to your sister" from the director and otherwise it was business as usual.
Last week one of the other colleague's husband had surgery for a recurrence of cancer. Everyone sprang into action, wanting to volunteer to do their yard work, house cleaning, child care, etc. and organizing meal vouchers, even cash for a house cleaner. They are planning a spa day for co-worker and other support. All of which is great but I couldn't help privately comparing and contrasting. Not that I'd ever raise the issue.
