We have some awesome neighbors who help DH with the shoveling and mowing. Of course, I have realized this is because we have become the "old folks" in the neighborhood, hahaha, but I sure do appreciate the help!
When DH had knee surgery and it got badly infected (he almost lost his leg) and was in a nursing home for 6 weeks for 24/7 IV antibiotics... I was so freakin' stressed all the time. However, people were incredibly kind when they heard the story. People went to visit him regularly, offered to feed our cats so I could stay overnight in the nursing home with him, shoveled my driveway when we had a storm that dumped 4 feet of snow on us, added special treats to my grocery purchases for him (Trader Joe's, awesome, kind people). Generous acts of true kindness to help alleviate my stress, to show some support for both of us... and I'm endlessly grateful, even 7 years later.
Sometimes, my TAs take over for me. I manage the organic chem labs and it's my responsibility to oversee the TAs and the labs, and I'm supposed to be there if there is a lab in session, even if I am not teaching. There are times when they know I'm struggling (especially since having a knee replacement last summer), when they can see how tired I am, and try to help out. They'll do some of my grading, teach my lecture, cover my lab when I'm teaching, or just say "we've got this, go home." It's not up to them to do this, it's not their responsibility, but I really appreciate it when they voluntarily increase their workload because they worry about me, can see I'm weary, or just plain like to "have my back!"
