While taking care of your mom, don't neglect yourself.
- Try to eat at least somewhat healthy.
- Get some moderate exercise.
- Get plenty of rest.
- Try to have at least some "ME" time every day.
- Try not to have too much to do with people who are stress triggers.
- You may want some noise cancelling headphones, so you can isolate yourself from people and other aggravations even when you are in the same room with them.
From personal experience, I've found that family are the biggest people aggravations. Fortunately, I live alone now.
Hope my suggestions are a help.
