How do I keep my career on track while dealing with my elderly mother?

You cannot give 100 percent to more than one thing, it's impossible. Only God is capable of that.
Something will get neglected. In the case of caregiving, if you are doing it at home, you are going to have to make some choices. How thin do you want to spread yourself, which will propel burnout? I am Speaking only from experience.

May God bless you.
