Depression

How do you all manage nannying while also being depressed? I’ve expressed to the family that I work with that I have been struggling mentally for some time now and am trying to do my best to be there for their kids. I feel horrible as I do not feel like myself and do not feel like I am able to effectively do my work. I hate it and it makes me feel like the worst. I am actively seeking help/medication but just wanted to know if anyone else experiences this and what you all do to help yourselves.
